High-Pressure Brass Regulator

The Victor 0781-1450 is a single-stage welding gas regulator built for cylinder supply. It handles argon and nitrogen service with a CGA-680 inlet and a 1/4 inch Swagelok outlet. Machined brass construction and a brass piston diaphragm support high-pressure applications up to 3000 psi delivery.

Steady Delivery Under Load

Single-stage design reduces pressure in one step from a maximum 3000 psi inlet. The 200 to 3000 psi delivery range is monitored by a 2 1/2 inch gauge, while a 4000 psi supply gauge tracks cylinder contents. ETL listing to UL252 confirms the build meets recognised safety standards for sustained high-pressure use.

CGA-680 Inlet Compatibility

This regulator fits cylinders equipped with a CGA-680 connection only. Buyers using cylinders with a different inlet standard cannot attach this unit without an adapter, which is not included. Verify your cylinder valve type before purchase.

Questions about this item

How much heat or noise does the 0781-1450 generate during continuous high-pressure use?

The regulator is a passive brass piston unit with no moving electrical parts, so it produces no measurable heat or noise regardless of inlet pressure up to 3000 psi.

Which hose or fitting must I already have to connect the 1/4 in Swagelok outlet on this regulator?

You need a 1/4 inch Swagelok-compatible tube fitting or hose assembly rated for at least 3000 psi to match the outlet connection.

Will the CGA-680 inlet on this regulator thread onto my existing argon or nitrogen cylinder valve?

Yes, CGA-680 is the standard inlet for argon and nitrogen cylinders, so it will thread directly onto those valve outlets.
