Harris Welding Supplies

Harris Products Group has been manufacturing precision gas equipment since 1914, making them one of the most trusted names in the welding and gas supply industry. WeldingMart carries a comprehensive selection of Harris welding supplies, with a deep catalog of specialty gas regulators engineered for industrial, commercial, and professional applications.

The Harris 742 Series oxygen regulators represent the pinnacle of high-pressure gas control, built to deliver consistent outlet pressure under demanding conditions. These regulators are available across a wide range of inlet pressure ratings and CGA connection configurations — including CGA 540 (oxygen), CGA 580 (nitrogen/argon), and specialty fittings — making them suitable for everything from precision cutting operations to large-scale industrial gas distribution systems.

Harris regulators are built with brass bodies, stainless steel internals, and dual-gauge layouts that provide real-time visibility of both cylinder pressure and working pressure. Whether you are running a production welding shop, a gas distribution facility, or a maintenance operation that depends on reliable gas flow, Harris regulators are engineered to perform.

WeldingMart stocks Harris specialty gas regulators, oxygen regulators, and related gas supply equipment from authorized inventory. All Harris products ship directly from our warehouse in Appleton, Wisconsin, with fast fulfillment and expert support from our welding supply team.
