I'm trying to get orings to seal on the guage stem in my aircylinder. What does everyone use to clean the surfaces where the oring sits? Do you put them in dry or apply some lube, if lubed, what type of lube?
I tried superlube grease on one oring. It held to 150 bar then started leaking

Hi in any of my gun orings when i replace them i put a thin film of silicone grease on them and just stretch them over
the fitting with an oring tool till then just start on then i roll them into possition.I clean the groves with balistol befour
installing.Most orings get nicked when they are installed or when the part is pushed back into the gun.When putting valves
barrels etc back into the gumn or anything else for that matter that has an oring just gently twist the thing back and forth while
pushig into place.There is a knack to it.On some orings people put a thin wrap of teflon tape over first then roll the oring on
then remove the tape.Be sure the oring is the correct size this will also cause problems.best of luck

Is it the green oring or black one in the pic, that is the issue. There are many different materials and hardness of orings. You may need to change the material of the oring to achieve a seal. When I zoom in on the pic it appears the green one has been deformed by the pressure, too soft?

It's the small black ring. I got some new ones from Cibles that are supposed to be the correct ones. The green ring is a little flat, I have new ones but this one isn't leaking. Not yet at least
