Anyone can tell me witch ring I have to change ?
The air also come from the end of the valve o-ring . Maybe I have to replace this o-ring 1x2 mm ?"sniperlabyo"No oring on the set screw, it's thread sealed, try tighten the screw, if still blows put thread sealer.
Thank you Ernest and gixxer3000 for those imformations"sniperlabyo"I been testing Viton oring 1X2 and buns 70 side by side after a tin the Viton seem to swell up a bit and the 70 got smaller, don't know if it matters but I have less leak issue with the Viton
