O2 Oxygen Sensor Bung in Stainless Steel Casting
Ningbo Suijin offers many high-quality bosses and bungs for exhaust systems. These components are designed to provide a secure and leak-free connection between exhaust pipes and other components, such as oxygen sensors or temperature probes. The bosses and bungs are also available in both stainless steel and mild steel, ensuring an option for every application.The high-quality bosses and bungs are a reliable and effective solution for exhaust system, providing a secure and leak-free connection for all components.
We stock a selection of cast and machined flanged Lambda/O2 bosses in Inconel 625 and Stainless Steel 316.Because of the weld on fitment and the special flanged shape this boss is highly durable and reliable.
The 304 Stainless Steel Exhaust Lambda boss Nut Weld-on M18 x 1.5 O2 Oxygen sensor are manufactured to the highest standards using top-quality materials and advanced manufacturing techniques. This ensures that they are durable, corrosion-resistant, and can withstand an exhaust system's high temperatures and pressures. The precision engineering and design also provide a perfect fit and a leak-free seal, which helps to prevent any loss of performance or efficiency in the exhaust system.
