Milton715-4 1/4" FNPT M Style Coupler - Pack of 4

I needed two new couplers to replace some I had that were over 30 years old and they were leaking air so my compressor was constantly cycling on and off to keep the pressure in the tank up. I was replacing the air hose and got the new couplers so I could replace both at the same time and everything worked great together and now my compressor holds air pressure with no leaks, so it runs a lot less. The Milton couplers came in a set of four which cost less than buying them separately and since I didn’t need four I have spare couplers available if I need one in the future.I highly recommend this Milton Brand Coupler because they are made of heavy duty quality components and will last many years.

This is by far the best quick change coupler I have ever bought! The quality is excellent! No leaks at all. When you plug your air tool into this coupler it just feels good and it seals perfect! Best thing of all is that it is made in the U.S.A ! This should last for years!

High Quality Milton Product

Dear lord why didn’t I discover this brand quality before?!! I have been using an air compressor to blow air out for my job and the hose that I purchased came with a coupler included but that coupler is pure junk because it would constantly leak. It was soooooooo annoying and frustrating.I am not an expert at this sort of stuff so I assume all air hose couplers leaked air but man was I completely wrong because this coupler does NOT leak at all. I could not believe it. I’m so happy. Excellent product and will continue buying this brand 👌

bought a couple of these to make a tire inflator kit. both of them were a little difficult to connect, especially with one of them being a quick disconnect schrader adapter (both things i attached them to were a little awkward to hold, which added to the difficulty). i usually had to try a few times because i wasn't pushing it far enough in when i let go of the collar.after a bit of research, i found out about milton's v style connectors--the notable feature for me being the push to connect (without having to hold the collar back). i probably would've bought those instead if i knew about them (plus they connect to the m style plugs as well as the v style plugs).i'll keep these, but the v style connectors were so much easier to connect. i'll just attach them to something that is a little easier to hold.if you're looking at these plugs, consider looking into milton's S-764/S-765 v style connectors. and also check out Milton's S-217 kit, it comes w/ 2 1/4 npt female connectors (S-764), as well as 2 1/4 npt male and 2 1/4 npt female plugs. it's cheaper to get the kit than get the 2 pack female connectors at the moment. All of these listed are the brass versions, and not the purple aluminum ones.

Glad I bought this set. I had so much trouble with so many of the female quick connects. Infuriating trying to stop them from leaking, more like blowing. These however, are very good, the price is right and they work. I recommend without hesitation.

Milton is a trusted quality product
