I have had nothing but good behavior from my Bulldog, but several people have claimed that using Teflon tape around the threads of the screw is useful. Some have gone as far as to use epoxy, but I do not like repairs which cannot be reversed.
I pulled the screw and placed silicone rtv sealant on the threads reinstalled,let it sit overnight then refilled to 3000psi and it seems to be holding pressure.was leaking about 500psi over night.I'll let it sit for 24 hours.i sprayed soapy water on fitting seems to be holding pressure.
well i degased to install a Depingger.the old school cut tubing placed inside the reservoir.well now that pitbull airguns(matt)has come out with his 3d printed Depingger,just got it in the mail.well now I'm going to install that,hoping it works better than that tubing.
