Thanks. I'm awaiting pricing now from Jinma. I'll be in China next week and will pick them up if the price is right. Otherwise I plan to replace the hose from the valve to the cylinder with no connections in between.
If you still want to try another O-ring, try a "double seal" profile. It will seal against a different part of the surface and has double sealing surfaces. McMaster-Carr has them.
