OVERVIEW

Heavy-Duty Replacement Gauge for Welding Regulators

Upgrade or repair your gas regulation equipment with this high-quality 2.00" Steel Pressure Gauge. Engineered for the demands of professional welders and fabricators, this gauge covers a pressure range of 0-100 PSI, making it the ideal choice for reading the low-pressure (delivery) side of many welding regulators, including those used for Argon, CO2, and Oxygen mixes. The steel housing offers superior protection compared to standard plastic gauges, ensuring a longer service life in tough shop environments.

The gauge features a Lower Back Mount (LBM) connection, a common standard for many industrial regulators and panel systems. This orientation allows the gauge to sit flush or properly aligned when threaded into the regulator body. The 2-inch diameter face is the industry standard size, providing a balance between compactness and readability. The scale is crisp and easy to read, helping you dial in the exact pressure required for your welding process or pneumatic tool.

Proper pressure monitoring is critical for weld quality and safety. A damaged or sticking gauge can lead to inconsistent gas flow, porosity in welds, or safety hazards. Replacing a faulty gauge with this steel unit is a cost-effective maintenance step that restores the functionality of your expensive regulator equipment. Please verify your regulator's thread size and mount orientation before ordering to ensure a perfect fit.

FAQ

Most 2-inch gauges typically feature a 1/4" NPT or 1/8" NPT thread. Please check your existing equipment to confirm the required thread size before purchasing.

While the pressure range is suitable for the delivery side of an oxygen regulator, all gauges used for oxygen must be specifically cleaned for oxygen service to prevent combustion hazards. Please verify if this specific item is 'Cleaned for Oxygen Service' on the packaging or contact support.

LBM stands for Lower Back Mount. This means the threaded connection protrudes from the back of the gauge case, near the bottom, rather than from the bottom edge of the circle.

This gauge is primarily designed for gases (pneumatic). While it may register hydraulic pressure, using a dry gauge on water lines can lead to corrosion or damage if not specifically rated for liquids. Liquid-filled gauges are better for hydraulic applications.

This gauge features a steel (STL) case, providing better durability and impact resistance than plastic alternatives.

Exceeding the maximum scale range can permanently damage the gauge's internal bourdon tube, rendering it inaccurate or broken. Always choose a gauge where your working pressure falls within the middle third of the scale.

No, thread sealant tape is usually sold separately. When installing, ensure you use a sealant compatible with the gas you are using (e.g., use oxygen-safe tape for oxygen systems).

CBM stands for Center Back Mount. If your regulator requires a Center Back Mount, this Lower Back Mount (LBM) gauge might not fit correctly or may interfere with the regulator body. Check the position of the port carefully.
