This tool is designed to help remove valves from the tank so you can inspect the inside or remove the valve for airlift.
The tool is made from stainless steel and has a HEX finish for added grip for removal.
The tool fits all scuba cylinders that have 5/8 DIN valves and also fits J-cylinder valves.
To use this tool, completely empty all gas from the cylinder and screw the tool onto the valve. Then simply roll up the tank and let the tool do the work or you can tap the tool with a hammer.
