- Mr. Gasket Ultra-Seal Exhaust Gaskets
Premium Ultra-Seal Exhaust Gaskets have the ability to conform to warped flanges for a tight seal and superior tensile strength to resist cracking. Their graphite facing withstands heat and allows easy removal.
Features:
- Manufactured from high-temperature steel core/graphite faced exhaust material
- Expanded steel core provides stability and maximum torque retention to eliminate gasket failure
Show More
- Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head
- Conforms to and seals minor surface irregularities
- High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load
- Can be trimmed if necessary for modified port applications
- For OE replacement, high-performance street, drag racing, and circle track
