Air Check Valve Stainless Steel Hex BSPP Female Thread One Way Air Check Valve for Gas, Oil, Water Pipe Connection(1/4”) Check Valve air Compressor Check Valve 1/4 Inch One Way Check Valve

The size fits perfect,don't know if it will pop off yet,haven't aired it up yet

It does exactly what it's supposed to do.

Appears well built, however it required 6 wraps of premium thread tape on each set of threads to seal. Threads are cut a hair to wide. the problem is its British Standard not National Standard pipe thread.

Sloppy sizing & threading, fittings installed won’t tighten and therefore LEAK !

The internal poppet and spring are not stainless. They corroded and the valve failed quickly.

I bought 8 pieces and 6 pieces had threads on one side which would hardly accept standard 1/4 inch male couplers

I put it on an on board air compressor in a vehicle and within 30 seconds the internals fell apart

As advertised

My handyman chose and installed it with no issues. Seems a well made item.

Installé dans une laveuse de réservoir à lait pour éliminer tout risque que l'acide de lavage entre en contact avec le détersif alcalin, ce qui crée une réaction chimique dégageant de la chaleur et des gaz nocifs.
