Fabricator’s Essential: 1/4″ Stainless Steel Weld-on Base Only

For custom fabrication projects requiring the replacement of damaged threads or the creation of new sensor ports, the 1/4″ Stainless Steel Weld-on Base is the fundamental building block. This component is the weldable boss portion only of the standard thermocouple mounting kit, machined from high-quality stainless steel. It is designed for fabricators who already possess the compression hardware or need to replace a damaged bung on a stainless steel exhaust manifold or downpipe.

High-Grade Construction

Manufactured to ensure perfect compatibility with stainless steel exhaust tubing (typically 304SS), this base prevents the issues associated with dissimilar metal welding. It features a robust wall thickness to prevent distortion during the welding process and provides a stable platform for the compression fitting threads. The precision-machined internal seat ensures that when a compression kit is applied, the ferrule seats correctly to seal exhaust gases effectively.

Application Scenarios

This part is ideal for:

Manifold Fabrication: Adding EGT ports to new custom headers during the build process.
Repair: Replacing stripped or damaged sensor bungs without scrapping the entire manifold.
Relocation: Moving EGT probes to a new location for better data resolution.
