Milton 5 In ONE Universal Quick Connect Industrial Coupler, 1/4" Female NPT, Air Hose Connection, Safety Exhaust Coupler, Single, Red (S-1750)

I bought this for my wife, because she has difficulty connecting the air hose to fill her bicyle tires, or car tires. It can be difficult for myself at times connecting some of my air tools as well. Well let me tell you this thing is worth every penny. So easy to connect and disconnect any air tool. Wish I had one of these years ago.

If you’re after a quick connect that’s as solid as a rock and as reliable as your best adventure buddy, this is where it’s at. The quality construction is immediately clear—this thing feels built to last through years of tire changes, air tools, and whatever else you throw at it. The precise air management is a game changer—no more guesswork or hissy surprises. It’s smooth, steady, and spot-on every time. Plus, the ease of use is fantastic—connecting it is effortless, like a perfect handshake. Robust enough for the roughest gearheads but simple enough for anyone to handle, this quick connect makes every air up job quicker, cleaner, and way more satisfying.

This coupler works with both my Milton "M" style fittings as well as "A" style (or Type B) I like the 2 step connector as it releases the air pressure before you disconnect. That's safer and easier on the ears if you have a long hose connected to it. The only negative I found is that if you drag this connector across the floor, it can pull the pressure release ring down and bleed off the pressure, requiring you to slide it back. Overall, this coupler is well built. No leaking from either type of fitting I use.

I’m a mechanic and i’ve injured my wrist due to a bad adaptor which was too hard to plug and unplug. This one, wow. It glides to easyly! You don’t have to put strenght to plug or unplug an air tool! My Life has completely changed since I installed it!! Every mechanic should have this. I’m curious to see in how much time it Will need to be replaced. I have it since 2 months and no problem to date. I’ll update this review if something goes bad.

I've had a lot of luck with Milton pneumatic tools and fittings, and this coupler is no different. I have 5-7 of these on various hoses around my home shop and they have worked out perfectly. Once you use a safety release quick coupler, especially if you're linking hoses together, it is so nice to release the pressure first before disconnection. The only thing about these is that sometimes you can inadvertently bump the air release when you don't want to. It doesn't happen often, but that is one thing that never happened with a standard coupler. Additionally, the univeral nature of the coupler is great, since I have a mix of fittings on air tools as I've bought them new and used, and have not really needed to switch to a standard fitting type. Overall, if you're looking for a high quality safety air coupler that works consistently, look no further.
