The Din Vinyl Valve Cap fits most DIN tank valves, including the newer conversion valves found on our tanks. It prevents the loss of your O-ring and keeps debris out of the valve when not in use. We respectfully remind you NOT to be the valve violator who uses a blast of gas from your tank to clear water from the valve cap -- it freaks other divers out, can panic the boat crew, and really annoys the divemaster.

DIN Vinyl Valve Cap for Scuba Tanks Features:

• Prevent moisture from gathering in the valve of your scuba tank
• Protects tank valve during transport
• Keeps dust and debris from collecting in the valve
• Helps distinguish your cylinders from your fellow divers'
