I use silicone grease for the o rings and moly paste and ballistol for the metal to metal parts like the breech. Don't use anything but pure silicone grease inside the pressurized air tube as it could become dangerous.
On orings use silicon grease I got a small tube for a few bucks at Lowe’s in the plumbing department. For grease I use a copper aniti seize grease great for keeping screws and bolts from seizing especially when different metals are screwed together. I also used it on the internal parts of guns with all grease a little goes a long way too much will attract dirt.
Certainly NO M olly or other burn able lube inside any high pressure area. Any lube is fine for exterior metal, pure silicone for anything that even might see air pressure. \
