Single-stage oxygen regulator with CGA-540 inlet, 0-60 psig delivery range and 1½-inch gauges

  • MaterialHAWA
  • TypeGas Regulators
  • Single-stage design simplifies setup for general oxygen use
  • CGA-540 inlet fits standard oxygen cylinders directly
  • 0-60 psig delivery range covers typical low-pressure welding tasks
  • Brass body with neoprene diaphragm resists corrosion and wear
  • ETL listed and 3,000 psig max inlet ensure safe high-pressure handling

Purpose and fit

This Victor specialty gas regulator is built for oxygen service on cylinders with a CGA-540 inlet. It suits welding shops, industrial maintenance crews and laboratory technicians who need a single-stage brass body regulator for general-purpose oxygen delivery.

Thermals noise power

The regulator operates without electrical power, fans or moving cooling parts, so it produces no noise and draws no current. Its brass body and neoprene diaphragm handle a maximum inlet pressure of 3,000 psig while delivering a steady 0 to 60 psig outlet range under normal flow conditions.

Deciding specification

The fixed delivery pressure range of 0 to 60 psig determines whether this regulator matches the process; systems that require higher or lower outlet pressure cannot use this unit. Buyers needing a different pressure span or a non-oxygen gas service should select another model.

Questions about this item

How do I install the Victor 0781-4241 regulator onto an oxygen cylinder without damaging the CGA-540 inlet?

Remove the cylinder valve cap, inspect the CGA-540 threads for debris, hand-thread the regulator inlet clockwise until seated, then tighten with a suitable wrench without over-torquing the brass body.

Which parts of the Victor 0781-4241 will need replacement after extended use?

The neoprene diaphragm and the internal seat assembly are the primary wear items; the 1-1/2 inch gauges should be checked for accuracy and replaced if the 3,000 psig supply gauge or 60 psig delivery gauge drift.

What is the first limit reached when the Victor 0781-4241 runs continuously at high flow?

The single-stage design means delivery pressure will rise as the cylinder pressure drops; the 60 psig upper delivery range is the practical limit before the relief valve activates or the set pressure cannot be held.
