OVERVIEW

1.5" Replacement Gauge for High-Pressure Applications

The MW-041 1.5" x 4000 PSI Gauge is a high-quality replacement component designed to restore the accuracy and safety of your gas regulation equipment. This gauge is specifically engineered for the high-pressure (inlet) side of welding regulators, allowing users to monitor the remaining contents of their gas cylinders effectively. With a scale ranging from 0 to 4000 PSI, it is suitable for use with Oxygen, Argon, Helium, Nitrogen, and CO2/Argon mixes commonly used in MIG and TIG welding processes.

Featuring a center back mount configuration with 1/8-inch NPT male threads, this gauge installs easily into the gauge port of most standard regulators. The installation process is straightforward, requiring only a wrench and appropriate thread sealant (such as Teflon tape approved for oxygen use where applicable). The 1.5-inch dial face is protected by a durable lens, ensuring the needle and markings remain visible despite the dust and sparks typical of a welding shop environment.

Don't let a faulty gauge compromise your weld quality or safety. A functioning high-pressure gauge is vital for leak detection and supply management. This unit serves as a direct replacement for damaged OEM gauges on many popular regulator models. It provides a cost-effective solution to extend the service life of your expensive regulator bodies without the need for complete replacement.

FAQ

This gauge has a 1/8-inch NPT (National Pipe Taper) thread, which is the standard size for most welding regulator gauge ports.

This is a high-pressure gauge (4000 PSI), designed to measure the tank (cylinder) pressure, not the working line pressure.

No, this gauge reads up to 4000 PSI. Acetylene gauges typically require a much lower scale (usually up to 400 PSI for contents) and have specific internal construction for safety with acetylene gas.

Unscrew the old gauge using a wrench. Apply a small amount of appropriate thread sealant (ensure it is oxygen-safe if using on oxygen) to the new gauge threads, and screw it into the port, tightening firmly with a wrench.

This is a back-mount gauge, meaning the threaded connection comes out of the center of the back of the gauge case.

It will fit most regulators that accept a 1/8" NPT thread and have a 1.5" gauge housing clearance. It is a very common standard size.

It is compatible with non-corrosive gases typically used in welding, such as Oxygen, Argon, CO2, Helium, and Nitrogen, provided the pressure range is appropriate.
