The Cressi Scuba Tank Valve Protector is compatible with DIN/Yoke cylinders and will protect your cylinder valve when it is not connected to a regulator, it will also prevent loss of your O-ring and keep debris out of the valve when not in use.

The Valve cap is also useful for identifying cylinders and is also commonly seen to be used to identify a full or empty cylinder.

The PVC Tank Valve Cap comes with a loop of the line so you can attach it to the cylinder’s valve. The Tank Valve Cap fits most tank valves.
