22080 - ESAB Purox Fuel Gas Valve Stem Assembly for W-300/W-200 Series

Technical Overview of the ESAB 22080 Fuel Gas Valve Stem

The ESAB 22080 is a precision-engineered replacement valve stem assembly designed specifically for the fuel gas line of Purox W-series welding handles. This component is critical for the safe and accurate regulation of fuel gases such as acetylene, propane, or natural gas within the torch body. Manufactured to original equipment specifications, it ensures a leak-proof seal and smooth rotational action, which are essential for maintaining a stable flame profile during welding, brazing, or heating operations.

The assembly features high-quality brass construction, offering excellent resistance to mechanical wear and oxidation. It is machined with specific thread pitches that match the internal tapping of Purox W-300, W-200, W-201, and W-202 handles. The stem includes the necessary packing or O-ring seals required to prevent gas bypass around the stem shaft. Proper seating of the valve is crucial; a worn valve stem can lead to flame fluctuations, flashbacks, or the inability to completely shut off the gas flow. Replacing the valve stem with this genuine ESAB part restores the torch's original performance parameters.

Technicians should verify the handle model before installation. While this stem fits the standard medium and heavy-duty Purox handles listed, it is distinct from the oxygen valve stem (often a different part number due to thread direction or seating geometry). Installation requires a standard wrench for the packing nut (if applicable) and should be performed in a clean environment to prevent contaminants from entering the gas passage.
