The Vevor oxygen and acetylene regulator set is designed for reliable gas regulation and clear pressure monitoring in welding applications. It features a CGA-540 oxygen inlet, a CGA-200 acetylene inlet for small MC acetylene cylinders, and dedicated outlet connections for each gas. Dual gauges provide 0-4000 PSI oxygen monitoring and 0-400 PSI acetylene monitoring for accurate readings during use. Its brass construction offers durable sealing and resistance to high-pressure working conditions. An extended T-handle allows smooth and convenient pressure adjustment.
