0781-4228 - Victor G150-60-540R Rear Entry Oxygen Regulator

Reliable Light Duty Oxygen Regulation

The Victor G150-60-540R Oxygen Regulator (SKU: 0781-4228) represents the gold standard in compact, light-duty gas control. Engineered by ESAB under the renowned Victor brand, this regulator is specifically designed to meet the needs of professionals in HVAC, light fabrication, and hobbyist metalworking. Its defining feature is the rear-entry inlet configuration, which makes it uniquely suited for use in portable cylinder totes and plastic carrying stands where space is at a premium and traditional side-entry regulators would be obstructive.

Constructed with a solid brass body, the G150 series maintains the robust build quality Victor is known for, scaled down for portability. Unlike many competitors that utilize plastic components for weight savings, this unit features a high-strength alloy bonnet. This material choice significantly enhances the regulator's durability, protecting the internal diaphragm and spring mechanisms from impact damage common in mobile work environments. The regulator is UL listed, ensuring it meets stringent safety and performance standards required for industrial use.

Precision control is achieved through an ergonomically designed, color-coded adjustment knob. The green coding provides immediate visual confirmation of gas service type (Oxygen), reducing the risk of cross-connection errors in busy workshops. The knob is textured for easy operation, even when wearing work gloves. The unit is equipped with dual 1.5-inch gauges featuring high-contrast faces, allowing operators to monitor both cylinder contents and delivery pressure with a quick glance. With a delivery range of 2 to 60 PSIG and a maximum inlet pressure rating of 3000 PSIG, the G150-60-540R offers versatile performance for cutting, brazing, and heating applications.

This model serves as a direct modern replacement for the legacy Victor SR6 and SR160 series regulators, offering improved ergonomics and updated materials while maintaining backward compatibility with standard CGA 540 cylinder connections and CGA 022 outlet hoses. Whether outfitting a mobile HVAC repair truck or setting up a home garage workshop, the Victor G150 provides the consistency and safety professionals demand.
