Sorry if this has already been asked before but I can’t seem to find anything on it. Is it possible to recut the threads on pneumatic cylinders or replace just the part that pops out of it?
Contact VEX support - any modifications to competition pneumatics is prohibited .

Sadly this isn’t allowed. You best bet is to deal with it or purchase/use another piston.
