Product Description

With the ever-increasing technology in performance and racing engines; supercharged, turbo charged, nitrous oxide and extreme compression ratios, a demand was created for stronger, more durable engine gaskets. Mr. Gasket, the originator of High Performance Gaskets, has met the challenge and developed performance gaskets in a variety of materials for all applications to meet the sealing demands of these engines. Mr. Gasket engine gaskets are the most advanced, tested and proven in the performance market today and earned the respect of many professional and sportsman racers.

Performance

  • Manufactured from high-temperature acrylic blend exhaust material.
  • Provides excellent sealing and durability.
  • Can be trimmed if necessary for modified port applications.
  • For OE replacement, high performance street, drag race and oval track use.

Ultra-Seal

  • 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 race and oval track use.

CopperSEAL

  • Manufactured from “Dead Soft” (solid) .043˝ thick copper material.
  • .051˝ embossment around each exhaust port to seal irregular surfaces. Total gasket thickness .094˝.
  • Provides excellent sealing and durability.
  • Conforms to and seals minor surface irregularities.
  • For high performance street, drag race, oval track and turbo-charged (extreme heat) applications.

Aluminum Layered

  • Reusable header, exhaust manifold and collector flange gaskets.
  • Manufactured from “Dead Soft” aluminum layers – .125˝ thick.
  • Conforms easily to surface irregularities (warped flanges).
  • Compresses down to .060˝ to create a tight leak-proof seal.
  • Will not shrink, deteriorate, or blow out – eliminating gasket leaks.
  • For high performance street, drag race and oval track use.

*MLS (Multi-Layered Steel)

  • Multi-Layered Steel (MLS) exhaust and header collector gaskets are designed for extreme cylinder pressures produced by high horsepower–high compression turbo-charged, supercharged and nitrous oxide injected engines.
  • Manufactured from three stainless steel layers, they resist corrosion, will not burn through or push out and maintain maximum fastener torque retention.
  • Stress formed inner and outer layer embossments act like springs that rebound under exhaust flange clamp load, creating force to seal extreme exhaust pressures. Total gasket thickness .075˝.
  • Will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel materials.
