Best Air Tool Fittings in 2022

Last update: November 22, 2022

Are air tools universal?

Most air tools will work with any air compressor. The size of the compressor you need depends on the air tools you plan to use. If you only need to use one light duty tool, then a small portable air compressor will work. For more heavy duty applications, you will need a larger compressor.

Are push to connect air fittings reliable?

Yes, push to connect air fittings are reliable. They are easy to install and require no tools. They are also leak-free and have a strong connection.

Can I use brass fittings for compressed air?

Yes, brass fittings can be used for compressed air. However, there are a few things to keep in mind. First, brass is a softer metal than steel, so it is more susceptible to wear and tear. Second, brass is not as strong as steel, so it is not recommended for use in high-pressure applications.

Can you use compression fittings on compressed air?

Compression fittings are commonly used to connect pieces of pipe or tubing together in plumbing or other fluid-carrying applications. In general, compression fittings are not recommended for use with compressed air or other gases, as the high pressure may cause the fitting to leak.


Heavy Duty RV and Camper Winterizing Blowout Plug Quick Connect Air Compressor | Easy Grip | Commercial Grade | Quick Connect Brass Fitting to Winterize Boats Motorhomes |Travel Trailers |Garden Hoses Review:


It was hilarious, annoying, yet funny to witness a group of people attempt to winterize my RV for me unsuccessfully for two hours since they were unaware of this small jem. After they left, my son and I completed the task in 20 minutes after I discovered the attachment. They claim that it "works as it should," and it does, but it certainly makes life easier. I'm grateful. I simply requested assistance because I was unsure of what to do when my husband passed away. I was able to complete the task by following their lead and discovering this attachment.



Camco Blow Out Plug With Brass Quick Connect-Aids In Removal of Water From Water Lines (36143) Review:


If you own a camper or even if you reside in a region of the country where it freezes and you want to blow up your garden hoses, you must have this tool. It is a reliable piece of hardware that was manufactured with care.The compressor's (line side) psi was set to approximately 25 psi for the camper blowout. There are many evaluations and opinions on the best pressure to apply, but 25 psi is sufficient to force the majority of the water out of the line while still being low enough to prevent harm. I noticed that some reviewers attempted to simply blow the lines out without using antifreeze; I wouldn't advise doing this. It only takes a small amount of residual water to build up in the bottom end of the pipes after blowing them out to cause issues over the winter.This is an add-on to how you usually prepare for winter. You shouldn't experience any issues if you blow up your lines and then apply antifreeze.

Milton (S-210) 1/4" NPT M-Style Coupler and Plug Kit, (12-Piece) Review:


This was sent immediately in OEM packaging by the seller, Tool Deals.This is a practical, affordable starter set that includes two female couplers, two female 1/4-inch pipe ends, and eight male ends. Most folks would probably enjoy that combination.The thing itself met expectations and was amazing. The "M" style coupler was invented by Milton, and in my opinion, the original is still the best.I have some air tools with Milton couplers that have been there for a long time. The exterior of some of the female couplers' brass is noticeably worn from being dragged across concrete over time, but the couplers themselves continue to function flawlessly with incredibly minimal leakage. The new ones, which I believe are still made in America, look just like the old ones.In actuality, none of these were necessities for me; instead, I bought them for my adult son, who recently acquired an air compressor and some air tools. The ones I now own should definitely outlive me, but if I ever need a new one for a different tool, I'll get Milton.



Milton S-217 1/4" NPT V Style Coupler and Plug Kit - 6 Piece Review:


To replace my shoddy Harbor Freight / Central Pneumatic couplers, I bought these a while back, but I soon forgot about them. I figured that while these were probably fantastic, I just never felt like making the effort to install them because the HF couplers got me by on a daily basis.Fast-forward to my wife's car's wheel hub replacement. As usual, the inferior HF coupler was leaking, which I had come to detest but accept. My impact wrench, which is often decent but not outstanding, was unable to crack one of the wheel lugs this time. My regulator was turned up to 120 PSI, but nothing changed. I finally removed every coupler in my garage in a fit of rage and started installing these, beginning with an impact wrench, an impact ratchet, and an air hammer. MIND BLOWING IN EVERY WAY! My impact wrench was hitting more forcefully and quickly, and these changes also gave my other tools new life, new power, and new utility—all without any leaks. Since I didn't choose the very best brands, I always assumed that my air tools might be a little below average, but I was mistaken.If you're anything like me, your collection of air tools cost you hundreds of dollars, while couplers just cost you a few pennies. Strangling an expensive tool with a cheap coupler seems absurd in retrospect. These have completely transformed my air tools, which formerly cost anywhere from $20 to $100 each. You spent a lot of money on a compressor, hoses, tools, sockets, and accessories to get your system up and running. Don't cut corners with the final $30 to create a fantastic system.I spent the money on a second coupler kit and corrected every tool in my shop after my experience with the first three items. learnt lessonFYI, I also conducted a brief experiment. I was able to couple a male HF coupler into a female V-style coupler but not a male V-style coupler into a female coupler (with minor leaks). You can probably get away by upgrading only the female couplers and your most often used male couplers if you don't want to upgrade your entire shop at once.



Primefit IK1001-2 1/4-Inch Industrial Brass Coupler Set with Male Plug, 2-Piece Review:


fantastic items I was pleasantly delighted to see that these goods have some weight to them, which is what you want in a product that will be dropped, banged up against things, and generally used roughly. They were available at the local farm store, so I got some. When I opened the packet, they felt as light as a feather. I returned them and bought a few sets of them.Knowing that I won't have to think about these again after they're fastened to my equipment gives me a huge sense of relief. The quick attach coupler operates smoothly and without a hitch. I tried it up to 125 psi and have no problems at all. My tools easily turned on and off. There was nothing hissing or leaking air. A truly fantastic product.



Milton (S-684-4) 1/4" MNPT Male Tank Valve Review:


Along with my new Milwaukee 18v cordless tyre inflation tool, I use this. The quick connect air chucks I also purchased: AstroAI Air Chuck, Heavy Duty Open Flow Lock On Tire Chuck with Clip for Inflator Gauge Compressor Accessories, Yellow (*the open flow version) attach into the 1/4 inch quick connect air chucks, and the inflation tool screws onto the tiny valve. The quick attach chuck naturally fits over the real tyre valve. Despite having a silly appearance, this method is awesome. There are no leaks, the tool gives a very accurate reading of the pressure, and no air escapes when the chuck is removed.



ColorFit by Milton Coupler & Plug Kit - (M-Style, Red) - 1/4" NPT, (14-Piece) Review:


These fittings are excellent. I didn't realise that these locks closed when not attached until I was replacing my old Harbor Freight "junk." The ones I replaced were lockable, which meant that all you needed to do to attach a tool was push firmly enough to overcome spring and/or air pressure. To release the collar, you must first draw it back and then push firmly enough to overcome pressure. It's a pretty small flaw, but I'll be replacing them because it annoys me every time I use them.



ColorFit by Milton HIGHFLOWPRO S-314VKIT Coupler & Plug Kit - (V-Style, Purple) - 1/4" NPT, (14-Piece) Review:


I've always used 1/4" type C plugs and couplers with 3/8" air hoses. This is more than plenty at the shop with an industrial 240 volt compressor and no pressure regulator. However, the power of my 30-gallon, 120-volt compressor at home is nowhere near as great. Even while I understood that, at least on paper, upgrading the plugs and couplers should compensate for the compressor's lack of capability, I pondered how much that might be. Considering that the plugs are composed of aluminum, I was also concerned about their durability. I ultimately made the decision to take the risk, and so far I'm quite delighted.In terms of the performance, WOW! An IR231 impact cannon was the first tool I used, and it felt like I was using a totally new kind of tool. Running without a load, the torque difference was clearly audible, and it became even more apparent when I actually put the tool to use. That was enough to convince me that I made the right choice, and other instruments also clearly increased in strength.I'm not sure how durable it will be yet. Since I switched to them, my air tools have not needed to be used at home very much, thus they have not been abused. I tend to take excellent care of my tools so they won't need to withstand regular abuse, but something will inevitably be dropped, banged, or whatever, and I'm still not sure if these will hold up like brass or steel plugs do. Although much lighter than aluminum, it doesn't feel as solid. Although I am aware that there are aluminum alloys available that are incredibly robust for their weight, Milton did not use one of those metals. I'm holding out on giving these 1 star until I've had them for a while and can assess how they hold up to greater wear.


How are air tool fittings measured?

Air tool fittings are measured by the size of their inner diameter (ID). The most common ID sizes are 1/4", 3/8" and 1/2".

How do you tell what air fitting you have?

There are a few ways to tell what air fitting you have. One way is to look at the end of the air hose. If it has a male end, it is a quick disconnect. If it has a female end, it is a plug and play. Another way to tell is by the color of the air hose. Quick disconnects are typically red, while plug and plays are blue.

How many times do you wrap Teflon tape?
