18697 - 50mm Oxygen Cylinder Pressure Gauge 0-4000 PSI Green Steel Case

Essential Replacement Oxygen Gauge for Regulators

Maintain the precision and safety of your gas distribution equipment with the Gauge 50mm * 4000PSI Green Steel. This high-quality replacement component is specifically engineered for the high-pressure side of oxygen regulators, serving as the primary indicator for cylinder content. A functioning high-pressure gauge is critical for workflow management, allowing welders to anticipate gas run-outs and plan cylinder changeovers effectively, thereby avoiding downtime in the middle of a weld or cut.

Precision and Readability

The gauge features a 50mm dial face, a standard size that fits the majority of industrial gas regulators from major brands. The scale reads from 0 to 4000 PSI, providing ample headroom for standard high-pressure oxygen cylinders. The needle movement is smooth and responsive, driven by a reliable internal mechanism that resists the mechanical shocks common in portable welding setups. The face is color-coded green, adhering to CGA (Compressed Gas Association) guidelines for oxygen equipment, which serves as an immediate visual confirmation of the gas type, enhancing shop safety protocols.

Rugged Steel Housing

In a welding environment, equipment is often exposed to sparks, heat, and rough handling. This gauge is encased in a steel housing (STL), offering significant durability advantages over brass or plastic alternatives. The steel case protects the sensitive internal components from physical damage and helps contain the mechanism in the unlikely event of a failure. The lens is designed to be scratch-resistant, ensuring that the pressure reading remains legible over the lifespan of the tool.

Installation and Maintenance

Replacing a gauge is a standard maintenance procedure that extends the life of your regulator. When installing this gauge, ensure that all threads are clean and that oxygen-safe Teflon tape or sealant is used if required (never use oil or grease on oxygen components). This gauge is suitable for use with heavy-duty, medium-duty, and light-duty oxygen regulators found in fabrication shops, automotive garages, and construction sites. By keeping your regulators equipped with accurate, easy-to-read gauges, you ensure consistent gas flow and pressure settings, which are vital for achieving high-quality welds and clean cuts.
