40A39 - ESAB 40A39 Replacement Valve Spring for V-12 Assembly

ESAB 40A39 Spring Valve V-12: Essential Repair Part

Keep your gas distribution and control equipment in top working condition with the ESAB 40A39 Spring Valve V-12. This small but vital component plays a huge role in the safety and efficiency of your oxy-fuel setup. Designed as a direct replacement for the spring inside V-12 valve assemblies, this part ensures that your valves close tightly and open smoothly. A worn or broken spring is a common cause of leaky valves, which not only wastes expensive gas but also poses a significant safety hazard in the workshop.

The ESAB 40A39 is manufactured to exact tolerances, ensuring it fits perfectly within the valve housing without binding or misalignment. Its spring rate is calibrated to provide the optimal resistance against the valve stem, giving the operator tactile feedback and precise control over gas flow. This is particularly important in applications requiring minute adjustments to the oxygen or fuel gas mixture, such as precision brazing or cutting.

Regular maintenance of your welding gear extends its lifespan and protects your investment. When rebuilding a V-12 valve, it is highly recommended to replace the spring along with the seals and seat. Metal fatigue is invisible but inevitable; replacing the spring with a fresh 40A39 unit eliminates the risk of failure down the line. This part is compatible with specific ESAB, Purox, and Oxweld equipment that utilizes the V-12 valve design.

Reliable Performance and Safety

Don't compromise on safety by using generic hardware store springs in your gas equipment. The ESAB 40A39 is made from specialized spring steel that resists taking a "set" (permanently compressing) even after thousands of cycles. It is also treated to resist corrosion, which can be a factor in environments with high humidity or chemical exposure. Ensure your team has reliable tools by maintaining them with genuine ESAB components available at Welders Supply.
