Milton Industries (S-766) 3/8" FNPT Female V-Style High-Flow Coupler

This is a very nice quick disconnect. It shoots the tool off the end quickly without losing much air. Even if you don't use the high flow connectors this is a nice female end.The real benefit of this is that you can use the normal flow and the high flow ends and switch back and forth. Some tools such as an impact wrench benefit from the high flow connector more than others. (paint sprayers might benefit as well) Milton makes great quality products that as far as I can tell haven't changed much over time. Quality brass with strong springs.Install it with teflon tape to make sure you don't have a leak. Put the tape on in the right direction so that screwing it on won't undo the tape. Brass is really the way to go if you don't like leaks and Milton is a great brand for compressor accessories.

I have been using couplers from various suppliers, and lots of ones from the discount tool store. However, the ones on the end of my main air hoses tend to see allot of use, and end up leaking after 3 to 6 months.This one has been in service for a couple of months, and shows no sign of premature leakage or wear. It is great.I should say that this coupler works differently from many other common couplers. Simply push into it and the male end locks into place.Similarly, there is not a need to detension the couplers to release, simply pull back on the release ring. I like that, but it is different from the other couplers I have. 10 year old kids will find this coupler easier to disconnect than the others which require more strength and additional dexterity.

I like how they work with the standard industrial type fittings. I noticed an immediate difference on how quickly my tires pump up. I noticed a difference at how much torque my impact gun has. I have yet to try a paint gun with it, but from what I hear, it will also make a difference. Great product, had no issues with quality whatsoever. I prefer brass to any other metal when it comes to air fittings.

I was surprised that a top name product would be a little buggy with release. It holds pressure fine and keeps its connection locked in place. I can still use it, but for being new, it seems like it has had 10 years of service with the locking collar. Any way I can live with it, just won't get 5 stars. I have tried cheaper products that are aluminum that don't have such issue, but long service life is questionable with those products. Any way I am keeping the quick release in service just have to deal with random sticky releases time to time.

I've changed all of my fittings to these Milton high flow versions. Why not take advantage of the superior air flow for better tool performance?

Do not have to pull the coupling ring out when inserting an air hose - just push in til it snaps. I like that.

Well made last longer than others

Milton fittings are the best. I had the purple aluminum ones, and the brass hold up to abuse WAY better.
