    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.

  • Manufactured from high-temperature steel core/graphite faced exhaust material
  • Expanded steel core provides stability and maximum torque retention to eliminate gasket failure
  • 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

  • Does this fit your vehicle?
