2Pack | Uffy Industrial Style Ball Swivel 1/4" Connect NPT Male Quick Air Tool M Fitting

I have two and neither leaks. Both swivel freely with no tension. A solid product so far. I did need a version the would fit on a male fitting and finally found it. ASIN B01GT3WW0M .

These are awesome, great product for good price. Thanks!

These were freshly machined and packaged. Good quality. A few of the edges are razor sharp. They will cut you and you won't know until you bleed moments later. Again, razor sharp!

Nice brass finish, fits well, greatly improved maneuverability of brad nailer. Only problem is that the first one broke at the neck when the nailer dropped from the third rung of ladder. Will see how long the second one lasts.

It works without leaking but there is a pretty serious pinch point, I picked up my air ratchet by the hose and had my finger touching where the swivel comes together and it was sharp enough to take a chunk out of my fingertip as it folded down on it.

These did leak--until I put thread locker on the main part, which seems to have eliminated the loosening which stopped the leak. Not perfect, but very useful for a framing nail gun and brad nailer, once "fixed."

Works great, smooth motion and no leaks. Thread sealant pre-applied too.

In building a large shed, the gaskets in my air fittings kept developing leaks because of all the angle pressure I was placing on the fittings. These swivel fittings greatly reduced the stress on the air lines. No further leaks. I'm impressed.
