JJCCR Counterlung T Piece threaded caps

These are threaded caps for the JJ-CCR T Pieces at the counterlung.

These hold the different plugs I have, and will continue to be producing to help me in my obsessive compulsive need to clean and dry my rebreather in interesting, and overly complicated ways.

Even if you don't use them for that - they, or something like them, are a good idea to protect the external threads on the T Pieces while your unit is disassembled.

I will probably add a closed off variation of these to this thing in the coming days.
