Compact and good fitt
The size fits perfect,don't know if it will pop off yet,haven't aired it up yet
J**N
Simple, but exactly the solution I needed.
It does exactly what it's supposed to do.
M**B
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.
A**N
Threads not to American standard 1/2” size pipe
Sloppy sizing & threading, fittings installed won’t tighten and therefore LEAK !
N**S
Material concerns
The internal poppet and spring are not stainless. They corroded and the valve failed quickly.
T**G
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
K**T
Would not recommend
I put it on an on board air compressor in a vehicle and within 30 seconds the internals fell apart
