Vixen AirVixen Air 1/2" NPT Male to Push to Connect (PTC) for 3/8" OD Hose Swivel Elbow - Bundle of four fittings VXA2123-4

Very well built and sealed dot airline perfect! Used on my air suspension and would definitely buy again.

Wasnt going to review, but feel the need to now. I've been using these for over a year. Never leaked once, even at the swivel. The swivel is designed and should be placed in a manner to relieve air line tension at the connection. The swivel is there as an option. If you put stress in the connection area, it might leak. So use common sense and make "easy" connections. Clean cuts on your air line also help in stress and tension inside the fitting.

Looks like good quality but 2 out of the 4 fittings leaked air around the quick connect fitting no good

Used for an air ride system, quality product as always.

I was initially very pleased until I looked through the threaded section and saw that the nice fat 1/2" diameter gets reduced to less than 1/4" as it passes into the swivelling quick-connect section. I considered enlarging the hole with a drill, but I have no idea how much "meat" there is to play with.Three stars seemed fair because no promises were made in the description about the adequacy of the through-hole yet it was reasonable to assume that with the other two diameters being 1/2" and 3/8" that there wouldn't be any significant restrictions in between.For high pressure air without high flow requirements, I'm sure these would work just fine.

Work just like it should go to elbows

For a 3/8 ptc fitting to neck down to a 3/16 orifice was kinda disappointing, but overall it's a nice piece

Used for air ride on A 1951 gmc truck. Much better than the plastic ones i had leaked
