57Y02 - 57Y02 Long Back Cap for WP-17/18/26 TIG Torches

High-Performance Long Back Cap for TIG Welding Torches

The 57Y02 Long Back Cap is a critical component designed for use with 17, 18, and 26 series TIG welding torches. Engineered to provide a secure seal and protect the tungsten electrode, this back cap is manufactured from high-quality, heat-resistant phenolic compounds that withstand the thermal stresses of continuous welding operations. It is specifically designed to accommodate full-length 7-inch (175mm) tungsten electrodes, allowing welders to maximize the lifespan of their consumables before requiring replacement or sharpening.

This component features a precision-molded thread ensuring compatibility with major torch brands including Weldcraft, Miller, Lincoln, CK Worldwide, and Radnor. The integrated O-ring provides a gas-tight seal, preventing atmospheric contamination of the shielding gas stream, which is essential for maintaining weld quality and preventing porosity. As a direct replacement for part number 57Y02, it integrates seamlessly into existing torch setups without the need for modification. The cap's ergonomic design allows for easy hand-tightening, ensuring a secure fit that prevents gas leakage during operation.
