Harris 301 Series Oxygen Regulator, CGA 540, 100 PSI Delivery

Reliable Precision for Industrial Oxygen Applications

The Harris Model 301-100-540 is a single-stage oxygen regulator engineered to meet the rigorous demands of light to medium-duty industrial applications. Designed with the professional in mind, this regulator combines a compact form factor with the rugged durability required in dynamic work environments. The unit features a solid brass body and a brass-painted zinc bonnet, materials selected for their resistance to corrosion and mechanical stress, ensuring a long service life even under frequent use.

Advanced Seat Technology

At the core of the Model 301's performance is Harris's proprietary one-piece encapsulated seat design. This innovative component integrates an internal filter that actively protects the PTFE Teflon seat from particulate contamination—a common cause of regulator failure. By preventing debris from entering the high-pressure seating area, the regulator maintains a positive seal and consistent performance over time. This design significantly reduces maintenance downtime and enhances the safety profile of the device.

Accurate Pressure Control

Precision is paramount in welding, cutting, and brazing operations. The Model 301 utilizes a high-quality neoprene diaphragm that offers superior sensitivity and response to pressure changes compared to standard materials. This allows for accurate pressure regulation up to 100 PSIG, providing the stable flow required for consistent flame characteristics. The regulator is equipped with dual 2-inch steel gauges that display both cylinder contents and delivery pressure on easy-to-read dual scales, allowing operators to monitor system status at a glance.

Safety and Compliance

Manufactured in the United States, the Harris 301-100-540 is UL listed, meeting stringent safety standards for compressed gas equipment. The ergonomic brass "T" screw handle allows for smooth, low-torque pressure adjustments, reducing operator fatigue. Backed by a comprehensive 7-year warranty, this regulator represents a secure investment for facilities managers and procurement specialists seeking reliable gas control solutions.
