Try as I might, I have been unable to find my answer through searching. I got a new Marauder pistol, and the gauge has parallel threads which apparently is the new and improved design. Well, mine has leaked since the first day i got it (500-700) psi overnight. The first thing I looked at was the gauge. Sure enough it was hardly finger tight after being degassed. I tightened it up, hoping that would fix the issue, and had a similar result the next morning. Tried all the usual fixes and had no luck. Ordered some 009 o-rings, and that has not fixed the issue either. My question is, does anyone know what the o-ring like material is that came from the factory? It does not appear to be an o-ring, but some type of gasket material perhaps? Any suggestions on fixing the leak are also appreciated. Has anyone had any luck with gasket material and a punch set to make a semi-custom remedy?
