Weld Fitting 1/8 NPT - 27 TPI - 6061 Aluminium Size: 20.4mm x 13mm

Overview

This precision-machined 6061 aluminium weld fitting provides a clean, professional solution for mounting 1/8 NPT sensors and fittings directly into fabricated manifolds, exhaust systems, and custom pipework. Essential for wideband oxygen sensor installations, boost pressure taps, and temperature sensor mounting in serious engine builds where drilling and tapping isn't an option.

Why You Need This

When fabricating custom intake manifolds, exhaust systems, or charge piping for turbo builds, you need sensor bungs that won't crack, corrode, or leak under boost. This 6061 aluminium weld fitting solves the common problem of adding sensor ports to fabricated components without compromising structural integrity. Unlike drilling and tapping directly into thin-wall tubing—which often results in cracked threads or blown-out holes under pressure—this bung welds cleanly into place and provides full-depth NPT threads that seal properly.

We see these used extensively in LS swap projects where custom intake manifolds need MAP sensor ports, RB25/RB26 builds requiring additional temperature monitoring points, and 2JZ turbo setups where exhaust manifold wideband bungs are essential for proper AFR monitoring. The 1/8 NPT thread accepts most Haltech wideband sensors, boost/vacuum sensors, and temperature probes directly. Professional fabricators rely on these bungs because they eliminate the guesswork—weld it in, machine flush if needed, and thread your sensor straight in.

ECU & System Compatibility

Accepts any 1/8 NPT threaded sensor including Haltech wideband oxygen sensors, MAP sensors, and temperature probes used with Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 ECU systems. Particularly useful for custom sensor installations in standalone EFI conversions where OEM sensor locations aren't available.
