Victor 0781-3504 Two Stage Oxygen Regulator

Product Description

The VICTOR 0781-3504 is a medium-duty, two-stage oxygen gas regulator designed for applications where consistent delivery pressure is critical as inlet pressure decreases. The two-stage design provides superior pressure regulation stability, making it well suited for work where fluctuating delivery pressure would compromise results or performance. The regulator body is built from die-forged brass for strength, and features a fabric-reinforced neoprene diaphragm, a precision machined nozzle for optimum flow control, and a stem-type seat mechanism that uses inlet pressure to aid in sealing. Certified to quality standards, every unit is tested before leaving the factory.

This regulator is intended for medium to large oxygen cylinders in medium-duty service. Typical applications include industrial welding, cutting, and gas distribution setups where steady downstream pressure is required across a range of cylinder fill levels. It is installed by welding professionals and industrial gas technicians in shop and field environments alike.

Key Features

• Two-stage regulation delivers stable delivery pressure as inlet pressure drops
• Die-forged brass body and spring housing cap for strength and durability
• Fabric-reinforced neoprene diaphragm for long service life
• Precision machined nozzle for optimum flow control
• Stem-type seat mechanism uses inlet pressure to assist sealing
• Delrin insert bushing for durability and easier adjustment
• Every regulator factory-tested for quality assurance

Compatibility

Designed as a medium-duty two-stage oxygen regulator suitable for use with medium to large compressed oxygen cylinders in industrial and welding applications.

Installation Notes

Installation should be performed by a qualified welding technician or industrial gas professional familiar with compressed gas equipment. Always close the cylinder valve and bleed all pressure from the regulator before connecting or disconnecting. Inspect the inlet fitting and seat for debris or damage before installation, and never use oil or grease on oxygen service fittings. Follow applicable compressed gas safety codes and the cylinder supplier guidelines during setup.
