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

Simple, but exactly the solution I needed.
It does exactly what it's supposed to do.

Is well built, but required excess thead tape
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.

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

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

Threads not to American standard 1/2” size pipe
Sloppy sizing & threading, fittings installed won’t tighten and therefore LEAK !

Would not recommend
I put it on an on board air compressor in a vehicle and within 30 seconds the internals fell apart

Ce clapet a régler mon problème de contamination de produit de lavage
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.
