Gray Ultra-Seal material takes gasket material to the next level.
These premium exhaust gaskets from Mr. Gasket are designed and constructed to improve the sealing of exhaust header flanges. Unlike standard exhaust gasket material, Ultra-Seal exhaust gaskets incorporate a graphite-impregnated facing and a steel-expanded metal core that reinforce and increase the tensile strength. This allows the gaskets to conform to warped flanges, giving them better sealing capabilities without deteriorating or cracking under the excessive heat and pressure that is common in the exhaust system.
- 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 to exhaust flanges and thermal conductivity to transfer heat away from cylinder head
- Conforms to and seals minor surface irregularities
- Can be trimmed if necessary for modified ports
- For OE replacement, high performance street, drag race and oval track
