Other FWB P70 cylinder oring and disassembly help needed.

[wildcj5]

A buddy picked up an old forgotten P70 junior and I am trying to bring it back to life. I have seals ordered for the action portion of the rifle.

Both removable cylinders popped within minutes of me airing them up. I fully expect it.

I have ordered a quick fill adapter for the gauge side but need an oring for the other end of the tube, plug to cylinder.

Because FWB considers them to have a ten year lifespan no parts/seals seem to be available when I search the web. Anyone know the size of the oring or have a source. I have not yet tried taking the cylinder apart.

Pictures of the leaking end and the hole the air vented from. The valve seems fine.

Thanks!

I started with a hair dryer to heat it up and get the end cap off. No dice. Moved on to a torch and got it hot enough I couldn’t hold it without a rag even in the opposite end. Clear gauge lens and gauge face got hot enough to warp and fall out. The inner gauge screw right out but both end plugs won’t budge. Open to suggestions.
