Miller Weldcraft 57Y04 Back Cap
This pack contains two short back caps designed for Miller Weldcraft TIG torches. They fit a wide range of models including the 17, 18 and 26 series as well as compatible PTA and PTW variants. The caps are sold new and ready for immediate workshop use.
Build quality and daily handling
The caps are manufactured by Miller Electric to match original torch specifications. Their short size designation allows easier access in confined joint configurations. Direct compatibility with listed torch bodies means no adapters are required during routine electrode changes.
Heat resistance and service life
As torch rear-end components, these caps withstand the thermal cycling inherent in TIG welding processes. They contain chemicals listed under California Proposition 65 relating to cancer and reproductive harm, so appropriate ventilation and personal protection should be observed during extended use.
