Gas Regulator for Inert Gases

The Victor 0781-9135 is a single-stage regulator built for inert gas cylinders using a CGA-580 inlet. It delivers outlet pressures up to 500 psi through a 1/4 inch 37-degree flared outlet. The brass body measures 2.5 inches in diameter and uses a neoprene diaphragm. It is listed to UL252 by ETL for general-purpose welding supply applications.

Cylinder and System Compatibility

Verify that your gas cylinder carries a CGA-580 valve outlet before ordering. The regulator accepts a maximum inlet pressure of 3,000 psi, shown on the 2-inch supply pressure gauge. Ensure your downstream hose or manifold uses a matching 1/4 inch 37-degree flared fitting. This model is intended only for inert gas service and is not rated for oxygen or fuel gases.

Brass Construction and Daily Use

The all-brass body and neoprene diaphragm resist corrosion from inert gases in workshop environments. Two-inch gauges provide clear reading of both supply and delivery pressures during operation. The single-stage design delivers consistent pressure without a second adjustment step. No accessories are included, so confirm you have the required flared fittings and hose ready for installation.
