Oxygen Mounting Notched Fitting Exhaust Review

The mounting bung is easy to weld onto any surfaces at an angle; Install the 45 degree weld bungs to replace or add oxygen sensor ports to any OEM or aftermarket exhaust or downpipe. The weld in bung and plug set features a standard thread size of M18*1.5 mm, which is suitable for most vehicles. The o2 sensor bung cap can be used to seal bungs that are not being used in the exhaust system. And the copper washer helps create a tight seal to prevent any exhaust leaks. (Note: If the gasket you received is not flat, please be assured that it does not affect the use). The oxygen sensor bungs feature tight sealing, wide clamping range, dust-proof and waterproof, easy installation and use. This angled bung kit is designed to be welded into the exhaust system, and includes a plug to seal the bung until installation can be completed.
