Review: The last coupler you'll ever need to buy — five profiles in one is the right idea executed perfectly - The pneumatic fitting compatibility landscape is a special kind of frustration that every air tool owner eventually runs into. Industrial profile, Automotive profile, ARO profile — pick the wrong one and your perfectly good air tool sits useless because the coupler says no. Milton's 5-in-1 universal coupler is the solution that should have existed decades ago and somehow we're all just now getting around to it. Five quick connect profiles in a single coupler body means whatever plug walks into the shop or shows up on a borrowed tool, it connects. No hunting through a drawer of adapters, no making a hardware store run mid-project, no zip tying a collection of individual couplers to the hose and hoping the right one is there when you need it. One coupler handles everything and that's exactly how it should work. 1/4" Female NPT threads onto any standard air line, compressor outlet, or hose fitting without drama. Thread quality is clean and sealed leak free on the first try with proper thread tape — no chasing fittings or dealing with the poorly machined threads that budget pneumatic hardware specializes in. Build quality is Milton which means it's built for real shop use rather than occasional garage duty. Solid brass construction, smooth coupler action that engages and releases cleanly under pressure without the stiff binding that cheap couplers develop after a handful of connect cycles. Flow capacity handles everything from finish nailers to impact wrenches without the restriction that undermines tool performance on undersized couplers. For anyone tired of the pneumatic fitting compatibility lottery, this is the coupler that ends the game permanently. Highly recommended.
Review: A must have for home or shop for saftey and speed!! - Its a game changer Love being able to attach the hose to tools but not pressurize the tool till your ready . I love this 2 stage quick coupler. Well built, quick grip rubber on the top make it so easy to secure to the fitting and doesnt allow air to pass through until you push that lockup which is nice cause you can still connect your hose but leave pressure out of what ever your using like grinder or sand blaster so noone accidentally hits the trigger or paddle or when you put the tools down no worries on if the trigger is gonna get pushed in and have your tool take off next to you.. has connected to every fitting I have and use and I am purchasing more for myself.

## Questions & Answers

**Q: Can this 5 n 1 quick connect be used on a pressure washer line?**
A: Pressure washers are at a really high pressure I doubt a fitting for compressed air is safe

**Q: Does this come in a 3/8 female to 3/8 female body?**
A: We have part# 1758, which is 3/8 by 3/8 FNPT

**Q: We’ll this work with P stile fittings**
A: No, P style is 3/8 automotive plug. This coupler is 1/4:.

**Q: Does this come as pictured above - with protective black bumpers?**
A: Mine did not.  But then again, when I bought mine, the photos of the item did not show those black bumpers.  Makes me think that this is a different/upgraded/later model.

### ⭐⭐⭐⭐⭐ One of the best
*by P***O on June 28, 2024*

I really like the a Milton 5 in One couplers. I originally used them just about everywhere but they are a bit bulky and can easily depressurize the tool you’re using by accidentally sliding the collar back when using them in the tool-end. I now use them exclusively on the manifold/regulator/filter ends. The one thing that makes me not want to use them on the tool-end is the very thing I favor on the manifold side, the ability to keep a hose plugged in without it being pressurized; just slip the collar towards you and you’re good to go and if you don’t want to leave the hose pressurized, slide the collar back when you’re done. On the tool-end, I prefer the Prevost S1 European/high flow safety couplers. (See last photo) They also prevent hose-whip and have the added benefit of having to press a button but even after that, the Prevost coupler doesn’t eject the fitting/hose like the Milton 5 in One does but there are a caveat, the Prevost ONLY accepts one style, whichever one you bought. I’ve heard some people have issues with hoses leaking because the a Milton 5 in One is exactly what it is named, you can use 5 different fittings with them; automotive (T), industrial (M), European/high flow (V), ARO (A) and Lincoln (L). I do love the Milton 5 in One, so far but I just find them a little too bulky on the tool-end. I do think that either way you choose to go, you can’t go wrong, it’s just a matter of personal preference.
