WWWBG-154000-B - 1.5-Inch Rear Mount High Pressure Gauge for Flowmeters (0-4000 PSI)

Precision High-Pressure Monitoring for Inert Gas Systems

The Western Enterprises PG15-4000R is a specialized pressure gauge designed to provide accurate readings for high-pressure cylinder contents. Engineered specifically for the welding and industrial gas sectors, this gauge features a compact 1.5-inch diameter dial, making it the ideal replacement or OEM component for flowmeters and compact regulators where space is at a premium. With a measurement range of 0 to 4000 PSI, it is fully capable of handling standard industrial gas cylinder pressures, ensuring operators can safely monitor gas levels from a full tank down to empty.

Constructed with durability in mind, the gauge utilizes a standard 1/8-inch NPT rear mount connection (center back mount), which is the industry standard for most flowmeter bodies and small regulators. This configuration allows the gauge to sit flush against the equipment, reducing the profile and minimizing the risk of impact damage during operation or transport. The internal mechanism is calibrated for reliability, providing consistent performance even in demanding workshop environments.

This specific model is designated for use with inert gases, making it suitable for Argon, Helium, Nitrogen, and Carbon Dioxide (CO2) mixtures commonly used in MIG and TIG welding processes. Proper pressure monitoring is critical for maintaining weld quality; knowing exactly how much gas remains in the cylinder prevents unexpected run-outs that can lead to porosity and weld defects. The clear, high-contrast face ensures that the needle position is legible at a glance, improving workflow efficiency and safety.

Whether you are repairing an existing flowmeter or assembling a new gas delivery system, the PG15-4000R offers the quality and precision associated with Western Enterprises components. Its robust design ensures a long service life, resisting the vibrations and minor shocks often encountered in industrial settings. Ensure your gas equipment is operating at peak performance with this essential high-pressure indicator.
