I can tell you first hand these valves suck!!!! been through so many of em i dont even bother carrying em anymore, yeah there cheap and truthfully i can make alot of money off em but now when ever i sell em i feel like im ripping my customer off i definently dont recommend them man. Do yourself a favor and go with Parkers, or atleast SMCs, you'll be so much happier that you did.if you decide you wanna get some though , shoot me a email and i'll set you up with some killer prices.
