Joseph G. ★★★★★

Welded this onto my exhaust for a wideband install and the zinc coating held up nicely. Fit was snug and the threads looked clean.

Eva F. ★★★★★

Threads matched my sensor perfectly and the zinc coating took weld without any spatter issues. Fit was dead on for my 18mm sensor, no chasing the threads needed.

Jason ★★★★★

Welded this mild steel bung into my downpipe for a wideband install and the threads took the sensor perfectly, no chasing needed. For the price of a single bung I expected thinner metal, but it's got some heft to it.
