Catalog Welding Gas Equipment Gas Regulators & Flowmeters Gas regulators control the pressure of gas. Gas flowmeters control gas flow, while flowmeter regulators control both gas flow and pressure. Gas switchover systems provide a continuous flow of gas to an application. ◀◀ ◀ ▶ ▶▶ Specialty Gas Regulator: Two Stage, CGA 580 Inlet, 1/4 in NPT M Outlet, 15 psig Gas Regulator: Single Stage, CGA 510 Inlet, 9/16"-18 M LH Outlet, 15 psig, Neoprene Diaphragm Gas Regulator: Single Stage, CGA 540 Inlet, 9/16"-18 M RH Outlet, 125 psig, Oxygen Gas Regulator: Single Stage, CGA 346 Inlet, 5/8"-18 F LH Outlet, 125 psig, Breathing Air Gas Regulator: Single Stage, CGA 580 Inlet, 1/4 in 37° Flared Tube Outlet, 250 psig High Purity Gas Regulator: Two Stage, CGA 660 Inlet, 1/4 in Tube Outlet, 25 psig High Purity Gas Regulator: Single Stage, CGA 580 Inlet, 1/4 in NPT F Outlet, 150 psig Gas Regulator: Single Stage, CGA 580 Inlet, 5/8"-18 F RH Outlet, 150 psig Flow Gauge Regulator: CGA 580 Inlet, 5/8"-18 F RH Outlet, 60 scfh (Argon) High Purity Gas Regulator: Single Stage, CGA 590 Inlet, 1/4 in Tube Outlet, 50 psig High Purity Gas Regulator: Two Stage, CGA 580 Inlet, 1/4 in Tube Outlet, 100 psig High Purity Gas Regulator: Single Stage, CGA 346 Inlet, 1/4 in NPT M Outlet, 50 psig High Purity Gas Regulator: Two Stage, CGA 660 Inlet, 1/4 in NPT F Outlet, 22 psig Gas Regulator: Single Stage, CGA 590 Inlet, 5/8"-18 F LH Outlet, 150 psig, Industrial Air Stage Flowmeter Regulator: CGA 320 Inlet, 5/8"-18 F RH Outlet, Flowmeter Regulator Gas Regulator: Single Stage, 1/4 in NPT F Inlet, 1/4 in NPT F Outlet, 250 psig High Purity Gas Regulator: Single Stage, 1/4 in NPT F Inlet, 1/4 in NPT F Outlet, 50 psig High Purity Gas Regulator: Single Stage, CGA 580 Inlet, 1/4 in NPT F Outlet, 22 psig High Purity Gas Regulator: Two Stage, CGA 580 Inlet, 1/4 in Tube Outlet, 100 psig High Purity Gas Regulator: Single Stage, 1/4 in NPT F Inlet, 1/4 in NPT F Outlet, 15 psig ◀◀ ◀ ▶ ▶▶
