What material is this collector adapter made from?

This collector adapter is constructed from 304 stainless steel, known for its good corrosion resistance, making it a suitable material for exhaust components.

What is the purpose of the O2 bung?

The O2 bung is a threaded port welded into the tubing that allows for the installation of an oxygen sensor. This is useful for engine tuning or monitoring exhaust gas conditions.

What does TIG welded mean for this part?

TIG welding is a high-quality welding process that creates strong, precise, and durable joints. For this collector adapter, it ensures the connections can withstand the heat and vibration of an exhaust system.

Product Details

If you're fabricating or modifying an exhaust system, you'll often run into situations where you need to connect pipes of different sizes or add a port for an oxygen sensor. This collector adapter from Stainless Works is designed to help you do just that. It takes a 3-inch, 3-bolt flange connection and steps it down to a 2-1/2 inch outside diameter tubing outlet, making it easier to mate different exhaust sections.

This adapter is made from 304 stainless steel, which is a solid choice for exhaust components because it resists corrosion well. The connections are TIG welded for a strong, durable bond that can handle the heat and vibration of an exhaust system. It also includes a pre-welded O2 sensor bung, conveniently placed about 2 inches from the flange, so you can easily install a sensor for engine management or monitoring.

This part is a universal fit, meaning it's intended for custom exhaust work where precise fitment to a specific vehicle isn't the primary concern. It's a well-built piece that should make your exhaust fabrication project a bit more straightforward.
