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

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.

This is a great air connector. The OEM one on my compressor, and the replacements from the import tool store, just didn't last long at all. This one is still going strong with no leaks.I especially like that it takes two operations to to disconnect a hose - depressurize, then release. Keeps knuckleheads from blowing hoses off and letting them fly around the job site and hurting somebody. I'm surprised OSHA doesn't require something like this.I've heard complaints of other brand's versions of this type of connector vibrating into de-pressurizing when the compressor is running. This one has never done that once. Just works.The O-rings on the outside that help you grip the connector when connecting/disconnecting a hose, can roll out of their groves, but you can grab it just as well without them. I think they're just eye candy.Really happy with this connector.

This is a pretty cool fitting, it works with all my male air fittings, quick connects instantly and having the secondary on/off function for the air at the fitting has come in handy several times when I didn’t even known I needed or wanted that feature.My only con would be I’m a lot more aware of this fitting than any I’ve used in the past. I don’t like just tossing the hose end on the floor or just letting it drag as I roll the hose up lol. It’s worth taking a little extra care to make it last tho.

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.

Good product and makes it easy to bleed off the air pressure

Works great and no leaking

Cons:- I have every standard and metric size wrench known to man, however, not a single one of them fit the hex part of this used to tighten the threaded connection, had to use an adjustable wrench to thread them on.- Kind of big and heavy compared to regular quick disconnect hose couplings.- There’s no instructions on how to use it, but it’s pretty simple to figure out.- Not sure how long it will last before what ever seals it internally starts to leak and no obvious way to rebuild it, but maybe that’ll never be a problem.- Kind of on the pricey side.- Using it on the tool end of my hose I notice it occasionally slips or gets caught on things resulting in the air bleeding from it. It needs a way to either lock it in position or reverse the direction you slide it so it doesn’t slide the pressure release sleeve open when dragging it around.Pros:- Works excellent at the stationary connections I plug my hoses into at the wall. Allows me to bleed all the air out of the hose before releasing it. I love it for this purpose.- It works exactly as advertised, bleeds air out of the tool before disconnecting it.- Very simple to use.- Seems to be superior quality.- Looks nice.I liked it enough that I ordered 2 more to go on the compressor end of my air hoses, now I can bleed all the air out of hoses before disconnecting them. The larger size and slightly heavier will be no big deal at that end and there’s a lot more air to bleed out when disconnecting the entire hose.

Works great! there is no back pressure taking attachments off.
