Product Details

The Stainless Works O2SS is a precision-engineered weld-on oxygen sensor bung designed for custom exhaust fabrication and header builds. This essential exhaust component allows you to install O2 sensors at the optimal location for accurate air-fuel ratio monitoring and engine tuning.

Key Features:

  • CNC machined from high-quality 303 stainless steel for superior corrosion resistance and durability
  • Precision lead-in chamfer design ensures easy O2 sensor installation without thread damage
  • Standard 18mm x 1.5 thread pitch fits most automotive oxygen sensors
  • Ideal for custom exhaust systems, header modifications, and turbo applications
  • Weld-on design allows permanent installation at any location on exhaust tubing

Installation Notes:

  • Can be welded to mild steel, stainless steel, or aluminized exhaust tubing
  • Anti-seize compound recommended on sensor threads during installation to prevent galling and ensure future removal
  • Position bung at least 18 inches downstream from cylinder head for accurate readings

Whether you're building a custom exhaust system, installing aftermarket headers, or adding wideband O2 sensors for tuning, the Stainless Works O2SS bung provides a professional-grade solution for oxygen sensor mounting.

I ordered a power bleeder from here. I had never heard of this site and decided to give it a go. I'm glad I did! The price was good and they shipped out fast.

This is my first order with you , so I will see how it goes.

Great price

Quick and easy

Found the item via Amazon, at a lower price than Amazom, and Paid via my Amazon account. Quick, easy, and less expensive. I shall return!

Quick

Great price,fast shipping, will buy from again. Thanks

Best price I could find

Fast, easy shopping

Great price on my Rampage rear bumper, good customer service, bit of a wait on the processing, but not horrible. After its all said and done, I'd shop here again.

A happy customer returns again

Quick and easy site to navigate!

Customer Service was excellent. Their online website provided accurate product description and when I called to double check, the gentlemen handled my request with ease and professionalism. Thank you for providing the best pricing on great automotive products. My wife and I purchased a WeatherTech trunk liner that would have cost me over $100 retail price but was able to purchase from Autoplicity for much less!!! Thanks guys and keep up the good work!!
