This Straight Threaded Valve is designed for use in cylinders containing oxygen, argon, carbon dioxide, nitrogen, helium and hydrogen, as well as welding gas mixtures. Leak tested, its precisely machined internal components meet the most stringent valve performance standards. Metal-to-metal seal below bonnet threads prevents pressure in the threads at top of valve body. Also, the direct-drive stem design with optimized O-ring seal reduces friction and operates at exceptionally low torque levels.
