DixonValve 2FF2-B Brass Manual Industrial Interchange Pneumatic Fitting, Socket, 1/4" Coupler x 1/4" - 18 NPTF Female Thread

Awesome. I am happy with the build quality and that it is air tight. My hose is not leaking after installing the first try. Never again will i buy a fitting from the big box store as they are total garbage.

this coupler has 6 latching balls rather than 3 like the couplers i've bought at the local big box store. I installed it on a new coiled air hose I just purchased and it makes a good, leak-free connection to the existing male-side air chuck I already had. The price is comparable to the one at the local store as well. Very pleased with the purchase.

Bought this for a Porter-Cable pancake 150 psi pancake compressor. (It's the ubiquitous one sold for years at Home Depot and other big box stores.) But it won't go on without an additional male-to-male adapter. I think most people will have this problem with this valve. Most compressors have a female fitting on the manifold where this attaches, requiring a male thread on the coupler valve.

Absolute best price for the quality. They hold up very well in an industrial environment

Made in the USA. Fixed my leaking problems that I had with the cheaper China versions. Has 6 retaining balls instead of 3 or 4. Holds very snuggly.

Well made and works perfectly.

just what we needed

These are the best couplers I used in a ling time. they seal perfectly and lock on strong, but yet are easy to un-couple.
