Stainless Steel Exhaust Pipe Weld Bung O2 Sensor Boss for 0.03-0.09 kg

1:Exhaust Weld Bung details introduction

Our 1.4308 stainless steel Exhaust Pipe weld bungs are precision CNC machined, in an ISO 9001 certified facility, are available in both Male and Female configurations and in sizes ranging from -4AN to -20AN, as well as NPT sizes.

-6AN Weld Bungs feature a standard 37° flared seating surface and 9/16"-18 SAE Male Thread. Our 1.4308 stainless steel Weld Bungs are a high quality, affordable choice for aluminum radiators, oil pans, tanks, and other custom fabrication projects.

Finish Line Factory O2 Sensor Weld Bungs are a must-have when building a new exhaust system for your car or if you’re converting an older car to use fuel injection.

Our 1.4308 stainless steel weld bungs may look like simple devices, but we takes them very seriously. They have spent several years researching, testing, and retesting to perfect what they feel are the finest adapters and fittings available.

Many people over tighten the weld bungs fitting on the adapter, which distorts the 37 degree seat, and may cause a leak. Both the threads and the seat surface face should have a drop or two of oil to smooth the tightening process.

A stainless steel exhaust pipe weld bung O2 sensor boss, also known as an O2 sensor bung or O2 sensor boss, is a component used in automotive exhaust systems. It provides a threaded port where an oxygen (O2) sensor can be installed to measure the oxygen content in the exhaust gases.

Here are some key details about the stainless steel exhaust pipe weld bung O2 sensor boss:

Material: It is typically made from stainless steel, which offers excellent corrosion resistance and durability, making it suitable for the high-temperature and corrosive environment of exhaust systems.

Design: The bung is usually a small cylindrical or hexagonal-shaped fitting with a threaded hole in the center. It is designed to be welded onto the exhaust pipe, providing a secure and sealed connection.

Thread Size: The bung has a specific thread size that matches the thread size of the O2 sensor. Common thread sizes for O2 sensors include M18x1.5, M12x1.25, and M10x1.25.

Installation: The bung is welded onto the exhaust pipe at the desired location, typically in the section closest to the engine, to ensure accurate measurement of exhaust gas composition. Proper welding techniques and equipment must be used to ensure a strong and leak-free connection.

Function: The O2 sensor boss provides a mounting point for the O2 sensor, which measures the oxygen level in the exhaust gases. This data is then used by the vehicle's engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion efficiency and emission control.

When installing a stainless steel exhaust pipe weld bung O2 sensor boss, it's important to ensure proper alignment and placement for accurate sensor readings. Additionally, it's essential to follow the manufacturer's recommendations for welding techniques, such as TIG (tungsten inert gas) welding, to ensure a secure and leak-free connection.
