I have a Reximex Mito with a slow leak , I think it’s on the air tube where it screws onto the pistol , does anybody have any names or links to good replacement o rings .
Any number of O-Ring suppliers on the bay, many happy to supply down to single pieces. You only need specific materials for things like CO2 (viton?) or for food use.
