The 3/4" X 14 NPSM cylinder plug is used when tumbling or painting scuba cylinders. It completely seals the neck of the tank to provide a secure barrier against external contaminants. The plug comes fully equipped with a robust NBR 214 / SH90 cylinder O-ring (ID 24.99mm x CS 3.53mm) to guarantee an absolute, leak-proof seal.
