Coilhose Pneumatics11-04BS Megaflow Ball Swivel Connector, 1/4-Inch, Male

Pricey, but works very well. No leaks. Hgh flow. Won't work in cheap home use type pvc air hose (have too small of connections), but works fine with Goodyear yellow hose.I have these on most of my hand held tools. Takes a good deal of strain off the hose.

Things probably changed over the years. The whole body is not smooth, but it has grooves on it from the manufacturing tools, even on the swivel ball. The swivel action is therefore jerky and "grinding"-like. I did not even try it on my tools and returned it right away. Pity, since other Coilhouse Pneumatics parts, like 1/4 inch automatic couples and connectors are perfect.

I think it is because of the very fact that the joint swivels, it is a bit of a hassle to get the connector into the coupling. That is the "nature of the beast" I guess. Connectors which are not swiveling kind are much easier to connect. So if you want ease of connecting then go with fixed non-swivel kind, but if you are concerned about the wear and tear a non-swiveling joint may put on air hose etc. then go with this one.I did not know this until I actually tried a swivel joint connector.

I have bought several coilhouse products and have never had any problems and this item is no different.

Apply one drop of air tool oil to the ball before use. The best quality part of its kind.

This IS the ULTIMATE 1/4" high-flow swivel fitting. Zero leaks, no hiss, snaps in automatically and plays well with other brand high-flow couplers. No compromise in flow when spinning or bending it.

I bought a few of these to try them out on my nailers/staplers. They work well if you spend a lot of time going up and down a ladder. I had one shear off when my stapler came off my toolbelt and hit the ground but the rest have worked well. It's especially handy when getting in tight places.

Obvious quality and great flow. I use these megaflow fittings on 3/8 hose and experience no noticeable pressure drop.
