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

Reliable High-Pressure Monitoring for Oxygen Systems

Ensure the safety and efficiency of your oxy-fuel welding and cutting operations with this premium 50mm High-Pressure Oxygen Gauge. Designed as a direct replacement for damaged or worn-out gauges on industrial gas regulators, this unit features a robust construction tailored for the rigors of the welding shop. The gauge is calibrated to measure cylinder contents accurately, providing a range from 0 to 4000 PSI. This range is essential for monitoring full oxygen cylinders, which typically arrive pressurized between 2000 and 3000 PSI, ensuring you always know exactly how much gas is remaining before starting a critical job.

Industry-Standard Safety Features

Safety is paramount when dealing with high-pressure compressed gases. This gauge utilizes the industry-standard green faceplate (or green markings), which universally signifies Oxygen service in the North American welding industry. This visual cue helps prevent dangerous cross-connection errors, ensuring that the gauge is only installed on oxygen equipment. The clear, high-contrast numerals allow operators to read pressure levels at a glance, reducing eye strain and minimizing the risk of misreading critical pressure data during operation.

Durable Steel Construction

Built to withstand the tough environment of metalworking, this gauge features a steel (STL) case. Unlike plastic-encased alternatives that can crack or shatter upon impact, the steel housing provides superior protection for the internal Bourdon tube mechanism. Whether it's accidental knocks against the cylinder cart or the vibration of a busy workshop, this gauge is engineered to maintain its accuracy and structural integrity. The 50mm (approximately 2-inch) diameter strikes the perfect balance between compactness and readability, fitting neatly onto most standard regulators without obstructing other controls.

Application and Compatibility

This gauge is an ideal solution for MRO (Maintenance, Repair, and Operations) professionals looking to refurbish existing gas equipment. It is compatible with a wide variety of oxygen regulators used in welding, cutting, and brazing applications. Replacing a broken gauge is a cost-effective alternative to replacing an entire regulator assembly. With its standard threading (typically 1/4" NPT for this class of gauge, though verification is recommended), installation is straightforward, allowing you to get your equipment back in service quickly. Trust in this high-pressure gauge to provide the consistent performance required for precision flame work.
