OVERVIEW

Restore Your Regulator's Functionality

A broken or unreadable gauge on your welding regulator isn't just an annoyance; it's a safety hazard and a productivity killer. The ESAB 999446 Replacement Gauge is the perfect solution for restoring your oxygen or high-pressure regulator to full working order. Featuring a 0-4000 PSI range, this gauge is designed to tell you exactly how much gas is left in your tank, preventing unexpected run-outs in the middle of a critical weld. The 2.5-inch face is significantly easier to read than smaller economy gauges, reducing eye strain and helping you monitor your gas supply with a quick glance.

Designed with the welder in mind, this gauge features industry-standard green markings, instantly identifying it as an oxygen-compatible component. This visual cue is essential for safety in busy shops where multiple gas types are used. The Lower Back Mount (LBM) design threads directly into the back of compatible regulator bodies, keeping the profile streamlined and the dial face oriented correctly for the operator. Don't let a cracked lens or stuck needle compromise your work; swap in this genuine ESAB replacement part to ensure accurate readings and safe operation.

Durable & Easy to Install

Installation is straightforward for anyone familiar with regulator maintenance. Simply depressurize the system, remove the old gauge, and thread in the new ESAB 999446 using an appropriate sealant or tape on the threads (ensure sealant is oxygen-safe). The robust construction ensures a long service life, even in environments exposed to dust, vibration, and handling. This gauge is an essential spare part for any fabrication shop, ensuring that your oxy-fuel or inert gas setups remain operational and safe.

FAQ

This gauge reads up to 4000 PSI.

The dial face has a diameter of 2.50 inches.

It features a Lower Back Mount (LBM) connection.

Yes, the green color coding and high-pressure range typically indicate suitability for Oxygen service (always verify cleanliness for oxygen use).

No, this is a high-pressure gauge (4000 PSI). Acetylene gauges are low pressure (typically up to 30 or 400 PSI) and use red color coding.

This is a contents gauge, designed to measure the high pressure remaining in the gas cylinder.

It likely refers to the case material being Plastic, or a specific product series designation.

It will fit regulators that accept a 2.5-inch gauge with a Lower Back Mount connection and standard threads (usually 1/4" NPT, but verify your specific regulator).
