SKU CH-V8TY-Z4JDM

Single-stage brass regulator with CGA-580 inlet and 100-1500 psi delivery range for argon, helium and nitrogen cylinders

  • Product typeWelding Supplies
  • Single-stage design delivers precise 100–1500 psi outlet control
  • Brass body and piston resist corrosion for long service life
  • CGA-580 inlet fits argon, helium and nitrogen cylinders directly
  • 2½ in 4000 psi supply gauge shows cylinder pressure at a glance
  • UL252 listed by ETL confirming high-pressure safety compliance

Single-Stage Argon Regulator

The Victor 0781-1428 is a single-stage gas regulator built for argon, helium and nitrogen cylinders. It connects to a CGA-580 inlet and delivers pressure from 100 to 1500 psi through a 1/4 inch Swagelok outlet. The machined brass body and brass piston diaphragm are listed to UL 252 by ETL for high-pressure service.

Installation Notes

Thread the CGA-580 nut onto the cylinder valve and tighten with a wrench; the 1/4 inch Swagelok outlet accepts compatible tubing or fittings. Check the 2 1/2 inch supply gauge reading against the 3000 psi maximum inlet rating before opening the valve. California Proposition 65 warns that the product contains a chemical known to cause cancer.

Pressure Range Limits

Single-stage construction means delivery pressure will rise as cylinder pressure falls, so the 100 to 1500 psi range requires periodic adjustment during long welds. The regulator is not suited for applications that demand constant outlet pressure without manual intervention. It is restricted from sale in certain states, so verify local availability before ordering.

Questions about this item

How can I confirm the Victor 0781-1428 regulator is working correctly after installation?

Verify the supply gauge reads up to 4,000 psi cylinder pressure and the delivery gauge shows your set pressure between 100 and 1500 psi with no leak at the CGA-580 inlet or 1/4 in Swagelok outlet.

What comes in the box with the Victor 0781-1428 and what must I purchase separately?

The regulator body with CGA-580 inlet and 1/4 in Swagelok outlet is included; hoses, cylinder adaptors and welding torches are not supplied and must be bought separately.

Which version of the Victor 0781-1428 should I choose for argon, helium or nitrogen at high pressure?

This single-stage brass model with CGA-580 inlet, 100 to 1500 psi delivery range and 3,000 psi max inlet is the only version listed for those gases.
