Sanderson’s copper collector gaskets are the answer to preventing persistent leakage at the header collector
Unlike composition fiber or combination fiber and metal gaskets, copper expands and contracts with the temperature of your exhaust. Since copper is soft, it compresses to form a better seal, and it won’t burn out! Copper gaskets have been used in aviation applications for years, and now they are available for automotive use with your Sanderson (and other brands) exhaust headers.
Sanderson copper collector gaskets are manufactured from 0.046″ thick dead soft copper and are easily annealed to return to their original condition. In other words, “They Are The Last Gaskets You Will Ever Need To Buy!”
- 0.046″ (3/64″) Thick
- Sold in Pairs
- Available in 2.5″, 3.0″, and 3.5″ Diameter (including Limefire 3-bolt and Jayster 4-bolt)
Use the image below to make certain you order the correct size collector gaskets for your headers.
Header collector gasket sealing is only as good as a properly secured exhaust system behind the headers. If the exhaust piping and mufflers are swaying back and forth with every motion of the vehicle it can strain the sealing accuracy of the collector gaskets and header flanges. Please be certain to use proper hangers that secure the exhaust piping. This simple task will provide years of trouble-free, accurate sealing.
Do not over-tighten the collector bolts. Having a slight gap between the collector rings is common (see the image below). This is why locking nuts are recommended for header collector retention.
