This Stainless Works collector adapter is a 3-bolt 304 stainless steel transition that connects a 3" flange to a 3" OD outlet while resisting corrosion and heat. All adapters are TIG welded for strength and precise fit. An O2 bung is welded into the tubing about 2" from the flange edge for sensor use. The adapter carries a limited lifetime warranty and is made in the USA.
