This a handy pro tool to have for use when installing or removing DIN valves from SCUBA cylinders. Constructed from solid 304 stainless steel with G 5/8" BSP threads on one end and compatible with both 200 Bar and 300 Bar outlets found on DIN valves used in SCUBA cylinders. Hand tighten it completely into the valve DIN outlet, then the bar allows you to tighten or loosen the valve without banging directly on the valve outlet and handwheel itself, or having to mar/deform the valve finish by hammering on a wrench set to a flat of the valve base or neck. This tool is especially useful for installing and removing compact in-line valves seen on many rebreather cylinders without damaging the DIN outlet or handwheel. Dimensions are {6 in | 15.2 cm} long and {1 in | 2.5 cm} in diameter.
