Victor G350 Plus Heavy-Duty Oxygen Regulator with CGA 540 Connection (0781-9433)

Industrial-Grade Oxygen Control You Can Rely On

The Victor G350 Plus oxygen regulator is a heavy-duty, single-stage regulator engineered for consistent, dependable performance in demanding welding, cutting, and heating applications. Whether you are working in a fabrication shop, on a construction site, or performing maintenance repairs, this regulator is built to handle daily use without compromising on quality or safety.

The regulator features a durable forged brass body paired with a high-strength zinc-aluminum alloy bonnet. This advanced bonnet material offers nearly twice the yield strength of traditional brass designs, providing superior protection for the internal diaphragm and seat assembly—even if the regulator takes an accidental hit in a busy workshop.

Designed for Safety and Convenience

The G350 Plus comes equipped with large 2.5-inch high-contrast gauges that are easy to read at a glance, allowing you to monitor cylinder and delivery pressures quickly and accurately. The pressure adjustment knob is color-coded in green for easy identification of the oxygen gas line, helping to prevent cross-connection errors during setup. The knob is also ergonomically contoured for a secure grip, even when you are wearing heavy welding gloves. The outlet connection is 9/16″-18 right-hand thread, which is standard for oxygen fuel gas lines.

Important Compatibility Note
This regulator features a CGA 540 inlet connection, which fits standard commercial oxygen cylinders with matching female valve threads. Please verify your cylinder connection type before purchasing.

How to Use This Regulator

Using the G350 Plus is straightforward. First, ensure your oxygen cylinder valve is closed. Attach the regulator to the cylinder by threading the CGA 540 inlet nut onto the cylinder valve and tightening it securely with a wrench. Connect the gas hose to the 9/16″-18 RH outlet fitting on the regulator. Before opening the cylinder valve, turn the pressure adjusting knob counterclockwise until it feels loose. Slowly open the cylinder valve, then adjust the knob clockwise until the delivery gauge shows your desired working pressure. Always follow standard safety practices when handling oxygen equipment.
