Victor 0781-1404 Single Stage High Pressure Regulator

Product Description

The VICTOR 0781-1404 is a heavy-duty, single-stage, high-capacity piston regulator designed for methane and hydrogen service. It delivers outlet pressure in the 50 to 750 psig range and accepts a maximum inlet pressure of 3000 psig, making it well suited for pressure vessel testing and dead-end testing applications. The body is machined brass with a brass housing cap. Actuation is piston-type brass with a Delrin cap bushing for smooth delivery pressure adjustments. The unit ships as a single piece and weighs 4.59 pounds.

This regulator is intended for industrial and specialty gas applications where high inlet pressures and precise single-stage delivery are required. Typical uses include pressure vessel testing, dead-end system testing, and other high-pressure methane or hydrogen distribution setups. The 350 CGA inlet connection with a bronze sintered filter pairs with a 1/4 inch Swagelok outlet connection fitted with a 1/4 inch stainless tube fitting. Licensed gas technicians and industrial piping professionals are the primary installers for this type of equipment.
