The ITW Miller Weldcraft 9-4 is a back cap insulator insert for TIG/GTAW welding torches. It provides pressure to the back end of the collet to force it against the collet body, ensuring a seal to prevent shielding gas leaks. The component is constructed from dielectric, heat-resistant material and is compatible with 9-series air-cooled and 20/25-series water-cooled torches.
