DIN50 safety caps seal to the bottle/canister with an O-ring behind a PTFE lip, so the O-ring is therefore not a wetted part. Unused ports can be closed with the stopcock. All ports can handle 1/8" or 1/16" OD tubing. A bottom-sealing barbed adapter to connect 1/8" (3.2 mm) ID tubing can be ordered separately.

• 1 cap, DIN50 threads, with stopcocks
