SMC Valves... 3/8 VS 1/2... sticking

I've heard that the SMC 3/8" Valves have a tendency to "stick"... where as the SMC 1/2" are made a little diffrently and almost never stick/go bad.

Any truth behind these alligations?

Thanks all!

that is true, ive ran em both. The 1/2 is definately the better way to go. Even tho they are rated on 150, the 3/8 start sticking if u have about 200psi in ur tank. If u wanna go the safe route u can get GC450's. No probs yet and niether have any1 else i know running em.

smc makes 2 3/8 valves,,the 150s will stick if ya go over 200 psi they also offer a 400 psi 3/8 valve they wont stick ,,the 1/2 valves are kick ass also,,,all i run is smc again,,,i tried a few other brands and came back to smc,,

WE have the biggest slection on valves check us out!!!

as always, 99.9% of the valves out there will not run well over there stated max pressure. but i would stick with SMC, they are the only valves i have ever used. i even ran some 1/4" from them. they were as quick as a 3/8" up, and a bit slower down. i thought they were perfect.

I have the 3/8 smc on the front of my truck and they don't stick.. They work great..

i have 8 3/8" smc's on my truck on 175psi, and never had one stick. About a week ago I got my first leaky valve in 1.5 years of daily driving, so I ordered a replacement

i have ran 3/8 and 1/2 smc for almost 2 years and no problems

im runnin 8 smc 3/8 valves no leaks at all plan on gettin 4 more

i got smc's in the front of my yota, havent had a problem with them sticking at all, and there 3/8, maybe in just lucky, there also like 5 years old.
