Frequently Asked Questions

Q: What thread size does this sensor weld bung use?

A: This sensor weld-on fitting bung uses a standard 20mm x 1.5 thread size, making it compatible with many diesel particulate matter (DPF) and soot sensors that share this thread pitch. Always verify your sensor's thread specification before purchasing.

Q: What material is the sensor weld bung made from?

A: The bung is made from a hardened, rustproof metal, built to withstand the demanding conditions of exhaust systems including high heat and vibration. Its durable construction ensures a long service life.

Q: How is this sensor bung installed?

A: This is a weld-on fitting, meaning it is welded directly onto the exhaust pipe or bung location using standard welding equipment. Once welded in place, it provides a permanent, leak-free mount for your particulate matter or soot sensor.

Q: Will this bung prevent exhaust leaks?

A: Yes. The precision-machined 20mm x 1.5 thread design ensures a secure, accurate connection between the bung and sensor, providing an excellent seal that prevents exhaust gas leaks and seepage around the sensor port.
