Keeping the Confusion Out of NPT Pipe Thread Dimensions

I recently had the pleasure of helping a caller solve a problem with a Super Air Nozzle.  He had measured the opening on the outlet of his air gun, and ordered accordingly…unfortunately, he didn’t know that 3/8 NPT did NOT correspond to a 3/8″ diameter of a threaded fitting.  I explained the reason for this, a while back, in a blog entitled “When Is A Half Inch Not A Half Inch? When It’s Half Inch Pipe, Of Course!

The ID of a 1/8 NPT threaded fitting is actually pretty close to 3/8". Here's a dimensions table that I reference often.

The ID of a 1/8 NPT threaded fitting is actually pretty close to 3/8″ (left.) Here’s a link to a dimensions table that I reference often to keep this (on right, a 3/8 NPT nozzle with an 1/8 NPT air gun) from happening.

 

As you can see, the Model 1105 3/8 NPT Super Air Nozzle will not fit the 0.405″ (not far at all from 3/8″ if measured with a ruler) ID of a 1/8 NPT threaded connection.  No matter; these are all catalog parts that we have plenty of stock on, so, after a brief discussion of pipe thread sizes, he got a Model 1103 1/8 NPT Super Air Nozzle, and it fits just fine:

Sometimes, an adapter is required for air guns that have straight threads.  Two common sizes for these are 5/8″-28 and 3/4″-32 – and we have adapters for both of these (call for details.) Other adapters are readily commercially available…you may find them in the plumbing aisle of your hardware store, or from a local pipe & pipe fitting supplier.  We’ve seen some air guns, though, that have a proprietary thread that doesn’t match up to anything else…in these cases, we have four types of Safety Air Guns on the shelf, ready to ship.

If you’d like to find out more about using quiet and efficient engineered Super Air Nozzles for your air gun applications, give me a call.

The Only Constant Around Here Is Growth

But if there’s a second constant around here, it’s excellence. And if there was a third, it was this guy…right up until the day he retired:

Joe Panfalone, Application Engineer extraordinaire, holding our bounty of product awards from 2013. He's retired since, but he's not...EVER...forgotten.

Joe Panfalone, Application Engineer extraordinaire, holding our bounty of product awards from 2013. He’s retired since, but he’s not…EVER…forgotten.

Another thing we don’t want to forget – in fact, I’m writing this as a reminder to YOU, dear reader, is that EXAIR products are up for ANOTHER four Plant Engineering Product of the Year Awards this year.  If you haven’t familiarized yourself with this year’s entries yet, there are some VERY cool products to choose from, and I highly encourage you to check them out(Disclaimer: I was an engineer BEFORE I came to EXAIR, and as such, I fully recognize the value that our esteemed colleagues bring to the table with THEIR entries, but I remain convinced that OURS are the clear winners here, as I’m sure you will too.)

Voting ends this Friday, January 8th 2016, so please hurry.  We’re honored to have gotten the nod in four categories this year:

ETC Dual CC SystemsAutomation and Controls: The competition is pretty stiff in this category…I’m sure you’ll recognize the names of some major players.  But, considering the wide range of applications, the potential cost savings by regulating the use of compressed air, and the convenience afforded by the ETC Dual Cabinet Cooler Systems, it’s a real contender.

HLRDVEnvironmental Health: With the ability to vacuum heavier tramp oils, thicker sludge, more viscous fluids, and “in the floor” cisterns, the High Lift Reversible Drum Vac makes fluid transfer and spill cleanup quick & easy.  They’re in stock for 30, 55, or 110 gallon drums. If you want a drum dolly, additional vacuum tools, or even the drum itself, check out our Deluxe and Premium Kits.  With all due respect to the other entries, it’s the clear winner in this category.

Compressed Air1006ss: This has been a long-awaited addition to our already broad selection of engineered air nozzles: the Back Blow Air Nozzles, available in two sizes, can handle blowing out pipe, tube, etc. with inside diameters from 7/8″ to 16″.  You can get one installed on one of our Safety Air Guns, and they’re available with Chip Shields, and extension pipes up to 6 feet in length.  This is the most innovative product being introduced in this category this year, for sure.

Fluid HandlingNo Drip Atomizing Nozzle: The patented design of the EXAIR No-Drip Atomizing Spray Nozzle offers a stand-alone nozzle capable of controlling liquid flow without requiring a liquid control solenoid.  When the air supply pressure is shut off, so is the liquid flow…just like that.

This feature is available on any of our Atomizing Spray Nozzles.  For safety, efficiency, cleanliness, it can’t be beat.

Remember, voting ends this Friday.  I know there are some great products to choose from, but all of us at EXAIR would genuinely appreciate your vote for our products.  Of course, if you ever have any questions about how these – or any of our Intelligent Compressed Air Products – can make life easier, give me a call.

Heavy Duty Safety Air Gun with Extensions up to 72″

Have you ever walked through a facility and looked up?  Most facilities have compressed air lines, electrical conduits, HVAC duct work, lighting ballast, beams, sprinkler systems, etc. located near the ceiling.  Can you imagine the amount of dirt and debris that has been collecting up there?  I received a phone call from a food processing plant.  They knew the necessity in keeping the entire area clean, even above their equipment.  They contacted me for help in trying to remove the dirt and debris from above all the structures near the ceiling.

72" Extension on Heavy Duty Safety Air Gun

72″ Extension on Heavy Duty Safety Air Gun

I suggested the model 1330-72 Heavy Duty Safety Air Gun with a 72” (1829mm) extension.  I also suggested a model 9053 swivel fitting to help angle the 2” (51mm) Flat Super Air Nozzle, installed at the end of the extension.  The customer would use a scissor lift to reach close to the ceiling and with the 72” (1829mm) extension, they could reach all the hard-to-get areas.  The 2” (51mm) Flat Super Air Nozzle would cover a larger area above HVAC duct work and racks of pipe and conduit.  When you add the model 9053 swivel fitting, it will help in directing the force of the compressed air at the top surfaces of your target.  Adding the Heavy Duty Safety Air Gun to this assembly, it makes a very reliable, durable system that can handle the banging and bumping in this application.

Dirt and dust can get everywhere, and EXAIR can help to remove it.  We carry a variety of Safety Air Guns, Super Air Nozzles, and lengths of extension pipes.  If you cannot reach it, give us a call and ask one of our Application Engineers for help.

Safety Air Gun Improves Aluminum Extruding Machining Process

I was doing some work around the house Saturday when I heard my wife shouting out from our laundry room….”Something is wrong with our dryer. This is the 3rd time I’ve restarted it and the clothes are still wet!”. Now having been in this situation before, I knew this meant that the exhaust was probably clogged with lint (again).

See, our laundry room runs parallel to our family room and the exhaust ducting goes up and then across the laundry room, across the family room and then exhausts on the side of the house. (I would like to find the person who thought this was a good idea!). I have thought about re-routing the ducting but the only other option would be to have the exhaust on the front of the house which will “never happen” (per my wife). So I usually end up taking my vacuum and attaching as many extensions as possible to reach as much of the ducting as I can. I have tried a few other methods with no success – like taking my leaf blower and, from the outside of the house, blow the lint back towards the laundry room and into a garbage can. (hint: make SURE your wife is not in the laundry room when attempting this…. They don’t react too well when they get covered in lint!)

This made me think of an application I worked on last week with an aluminum extrusion company. The customer cuts lengths of aluminum siding from 1’ up to 10’ in length and, standing at one end of the material, are using a standard blow gun to try and blow out the chips but are unsuccessful. They reviewed our website but were still unsure what product may fit their needs best, so they gave us a call.

We discussed their application and the customer was able to email pictures. After reviewing the pictures I recommended using one of our Soft Grip Safety Air Guns with our Model # HP1125, 2” Flat High Power Super Air Nozzle and a 72” extension.  The Soft Grip Safety Air Gun is constructed of cast aluminum and includes a hook for hanging in a convenient location. The Model # HP1125, 2” High Power Flat Super Air Nozzle, produces 2.2 lbs. of force @ 80 PSIG and utilizes 37 SCFM with a sound level of 83 dBA. This would also meet or exceed the OSHA standards for safety, per Standard 1910.242(b) for 30 psi dead end pressure, and allowable noise exposure per Standard 29 CFR – 1910.95(a).

Promo’s: Everybody Loves Free Stuff

I have been wanting to purchase a pair of good quality headphones for a while now and with vacation coming next week, I figured now was a good time to make my purchase. I was pretty set on the manufacturer but the tough choice for me was going to be if I wanted a set of earbuds (that fit directly in the ear) or a more traditional pair of “over the ear” headphones. smiley_face_headphones_tshirt-d23545082320430684226v7p_325I tried about 4 different pairs of over the ear units to see what the quality of sound was versus the feel/comfort and was pleasantly surprised but was still leaning towards earbuds. Unfortunately, due to health/cleanliness issues, you aren’t allowed to try on earbuds – which makes sense. So if I was going to go the earbud route I wanted to make sure I had all my questions answered so I decided to get a salesperson to assist me.

We went over features/benefits but this only made me question myself more. Seeing that I was struggling with a decision, the salesperson decided to make my choice a little easier – he mentioned that his store, along with the manufacturer, were offering a free promo but only if I purchased a set of earbuds (at a certain price of course). Due to the sound quality and trusted manufacturer, I was leaning towards a set of earbuds anyway, but hey – who doesn’t love FREE stuff? What they were offering was a free carrying case (not really free since it was already in the box), a free 2 year service agreement ($37 value) and a $25 gift card to their store.

Of course, I took advantage of their offer and made the purchase. After listening to the earbuds while I finished my packing, I couldn’t be happier with my selection.

At EXAIR, we occasionally run promotional offers too. From now through September 30th, 2014, if you purchase one of our Precision Safety Air Guns, Soft Grip Safety Air Guns or our Heavy Duty Safety Air Guns (with or without an Aluminum extension), you will receive a FREE Chip Shield.

Free Chip Shield Promo
The polycarbonate Chip Shield, meeting OSHA 1910-242(b) for compressed air use, offers the operator safe and smart protection from flying debris as well as any splashing. Not to mention that all of our Safety Air Guns incorporate one of our Engineered Super Air Nozzles that meet or exceed the same OSHA standard and reduce air consumption and sound level.

This offer is good for all three models of our Safety Air Guns:

  • Durable, Lightweight, Precision Airflow – The Precision Safety Air Gun is a small ergonomic gun good for light duty cleaning or blowoff and fits well in smaller hands. It also has a strong focused blast of air capable of reaching into tight spaces.
  • Versatile, Industrial Duty, Most Popular – The Soft Grip Safety Air Gun is our most popular gun cast from aluminum with a comfortable four finger trigger to reduce fatigue over long periods. A large variety of air nozzle options provides a solution for light to heavy duty blowoff applications.
  • Powerful, Rugged, Robust – The Heavy Duty Safety Air Gun is the powerhouse you need for the harshest environments and stubborn blowoff applications. It is outfitted with many of our most powerful nozzles to provide the highest force upon your application.

To learn more about this offer, please visit our website www.EXAIR.com or if you have a specific application you would like to discuss, give us a call at 1-800-903-9247.

Everybody Wants Options II

Justin Nicholl, I hear you loud and clear about how Everybody Wants Options. I would go so far as to say a lot of people NEED options. This was evident in an application that I had the pleasure of assisting a caller with recently. They make plastic parts for the automotive industry, and manually remove them from a conveyor line, where the operators experience a nuisance static shock. This static charge also presents a problem when the parts are packaged for shipping, so there are two great reasons for getting rid of it right there.

On to the options: they weren’t sure if they wanted to mount something over the conveyor (like a Super Ion Air Knife or Ion Air Cannon,) or if they wanted to have manual, precise control (as with an Ion Air Gun.) I recommended that they try the Ion Air Gun…for ease of setup, it can’t be beat: you can literally go from opening the box to blowing ionized air in a matter of minutes, provided you’ve got a compressed air line and an electrical outlet within reach. If it is indeed successful in eliminating the static charge (and this is a VERY common & successful application,) then the only question is: Will the operator want to have another hand free? If so, they can return the Ion Air Gun for full credit per our 30 Day Unconditional Guarantee, and get either the Super Ion Air Knife or Ion Air Cannon; whichever they choose. In fact, it’s very likely that using the Ion Air Gun for a little while will better inform their decision.

EXAIR Static Eliminators: Mount in place, or hold in your hand.

EXAIR product lines, across the board, are rife with options. I wrote a while back about a purchasing agent who got a request for “the largest, most powerful air gun they’ve got” and ordered a 6′ Super Blast Safety Air Gun (with a 1-1/4” NPT connection, 6 foot extension, and a whopping 23lbs of force) when they just wanted to blow off some chips from their machine tools. Again, we used the 30 Day Unconditional Guarantee to get them a 6″ Heavy Duty Safety Air Gun (3/8” NPT connection, 6 inch extension, and a very usable 13oz of force.)

1218-6 1310-6 blog

Another user recently tried a Stainless Steel Line Vac – the product they needed to convey was too abrasive for an aluminum Line Vac – but they just weren’t getting the conveyance rate they wanted. No problem…the Model 150200 2” Heavy Duty Line Vac is made of an abrasion resistant hardened alloy, and boosts conveyance performance dramatically. The dimensions were the same, so the new one dropped right in, saving them from exploring the option of re-plumbing their lines.

Regardless of your compressed air product needs, EXAIR is the most likely solution:

*Super Air Knives are available in lengths from 3” to 108”. They come in aluminum, 303 or 316 grade Stainless Steel, and PVDF plastic (with Hastelloy-C fasteners and Teflon shims for the most aggressive installations.) This is, by far, the most options you’ll find in the industry. And they’re all in stock…waiting until next week doesn’t have to be an option.

*Cabinet Cooler Systems come in capacities from 550 BTU/hr to 5,600 BTU/hr. Whether your enclosure needs NEMA 12 (oil tight, dust tight, indoor duty), NEMA 4 (splash resistant) or NEMA 4X (corrosion resistant,) we’ve got it. And yes, they’re in stock.

*If you need to move a lot of air, or draw a vacuum, our Adjustable Air Amplifiers and Adjustable E-Vacs, respectively, offer you infinite options in range of performance with the simple twist of a locking ring.

You want options? We’ve got them. You want help narrowing them down? Call us.

Multi-tools, Adjustable Wrenches, and Vortex Tubes

I like tools and gadgets that can perform a variety of functions. From the Swiss Army Knife, to the multi-tools by Leatherman, Gerber, etc., I’m a sucker for anything that might offer me the chance to NOT dig through my toolbox for something that’s probably not there because it didn’t get put back the last time.

That’s why another of my favorite tools is the adjustable spanner…you may know it as the Crescent, or perhaps, the “all sixteenths,” wrench. Its popularity is cemented in American legend, as pioneering aviators Charles Lindbergh and Richard Byrd both famously included them in the scant provisions they took with them on their long flights across the Atlantic and to the North Pole, respectively. Remember, this was back when every single ounce of weight that someone took on a plane with them had to be carefully considered. Which, come to think of it, isn’t that much different than commercial flight luggage constraints today. But I digress.

Lindbergh took only "gasoline, sandwiches, a bottle of water, and a Crescent wrench and pliers" on his famous flight.

Lindbergh took only “gasoline, sandwiches, a bottle of water, and a Crescent wrench and pliers” on his famous flight.

One other thing this tool is sometimes called is the “Crescent hammer.” Dear reader, don’t do that to such a fine instrument. Seriously; go back to the toolbox that it came from…odds are, you’ve got a real hammer there. It will strike the handle end of the screwdriver that you intend to use as a chisel much squarer. While you’re there, get your safety glasses too. You’re welcome.

Now, it’s not always a problem to use things for applications other than what they were intended for…not always. In fact, I had the pleasure of helping someone do just that with a Vortex Tube recently. During the assembly of the electrical connectors they make, they put a small dab of sealant inside. When wire is inserted by the user, this sealant helps hold it in place, and protects the bare end from corrosion. They were, however, putting more than they needed into the connectors, and were looking for a way to quickly heat the piece, which would thin out the sealant and produce an even coating inside, allowing the rest to be recovered and reused.

They were already familiar with EXAIR products, since they’re a big user of our Safety Air Guns. The caller had found our Vortex Tubes in his copy of our catalog, and was wondering if he could use the hot air flow for this. He knew what temperature he needed to reach, but didn’t have a feel for how much (or little) air flow would be needed to do the job. This was no problem, since our Model 3930 Cooling Kit comes with a Medium Vortex Tube and ten different Generators, which allows for a range of hot flows from 2 to 32 SCFM (56 to 906 SLPM), and temperatures from 96° to 261°F (35° to 127°C).

3930

If you’ve got an application that you want to use a Vortex Tube for – be it cold or hot air that you’re after – give us a call. Oh, and I was just kidding about the screwdriver; I know you have a chisel, and, like mine, it’s somewhere. Somewhere…
