So what youre saying is that you know the valve failed because of your lack of preventative maintenance, and because of this you can't reccommend that valve to anyone else? :think:LowBlue02 said:Neither. Check SSM, tons of people are having problems with them leaking.
I'd go with Parkers, personally. But you have to find the right Parker valve, not all of them are the same. Some suck, some are unbeatable.
My SMC's have been great, but a couple months ago one of the rear lift valves started leaking into the bag. I know it's cause of the passed oil from my compressor, and the fact that I've never drained my tanks in over a year, but because of this I don't know if I can recommend them.
