ESAB Linde WC-1 Inert Gas Regulator No.568261 is a two-stage regulator that provides precise delivery pressure control in the 0-500 psi range with a minimum flow capacity of 1060 cfh at 500 psi delivery pressure. Suitable for use with water-pumped inert gases like argon and helium, it connects to cylinders via a CGA 580 inlet fitting. It features a pressure feedback line to maintain good regulation under all flow conditions and a bursting disc for added safety. The regulator comes with a 4000 psi inlet pressure gauge and is designed for connection to flared 1/4" O.D. tubing at the outlet.
