17967 - ESAB Valve Seat and Stem Assembly Replacement Part

Precision Replacement: ESAB Valve Seat/Stem Assembly

The ESAB 17967 Valve Seat/Stem Assembly is a professional-grade repair part designed for the maintenance of industrial gas control equipment. In the world of welding and cutting, the regulator and torch valves are the gatekeepers of energy. They control the flow of volatile gases from high-pressure cylinders to the point of work. The valve seat and stem are the dynamic heart of this system, moving constantly to modulate flow and shut off supply. Because they are moving parts subjected to high pressure, they are the most common wear items in gas apparatus. This assembly is the OEM solution for revitalizing worn-out units.

Constructed from precision-machined brass and specialized sealing compounds, this assembly is built to tolerate the rigors of daily industrial use. The stem is machined to strict tolerances to ensure smooth travel within the valve body, preventing binding or wobbling that could lead to inconsistent gas delivery. The seat is designed to withstand the compressive forces of the valve closing mechanism without deforming permanently, ensuring a positive shut-off every time. This is particularly important for preventing regulator creep, a condition where the delivery pressure slowly rises when the torch valves are closed, which can damage downstream hoses and equipment.

Professional repair technicians and safety-conscious welders know that using generic or ill-fitting parts in gas equipment is a risk not worth taking. The ESAB 17967 ensures compatibility and performance matching the original factory build. It is suitable for a range of ESAB and legacy Victor gas equipment models. When installing, ensure all mating surfaces are clean and free of oil or grease, as contaminants can be hazardous in oxygen service. This assembly is an essential inventory item for maintenance departments and mobile repair rigs.
