Mr. Gasket Ultra-Seal Steel Core Graphite Faced Header Gasket

Universal Fitment for High Performance Street, Drag Race, and Oval Track Applications

7594

Overview:

The Mr. Gasket Ultra-Seal Steel Core Graphite Faced Header Gasket is engineered to deliver reliable sealing performance under extreme conditions. Designed for use in high-performance street vehicles, drag racing, and oval track competition, this gasket ensures a durable and leak-free seal between the exhaust header or manifold and the cylinder head. Its advanced construction provides excellent heat resistance and stability, making it an ideal replacement for original equipment or an upgrade for performance applications.

Whether you are rebuilding your engine or upgrading your exhaust system, the Ultra-Seal gasket offers peace of mind by preventing exhaust leaks that can reduce power and damage components. Its ability to conform to minor surface imperfections helps maintain a tight seal even on older or modified flanges.

Key Features:

Built to withstand the rigors of high heat and pressure, the Mr. Gasket Ultra-Seal gasket incorporates several advanced features:

• Manufactured from high-temperature steel core with a graphite-faced exhaust material for superior durability
• Expanded steel core construction provides enhanced stability and maximum torque retention to prevent gasket failure
• Graphite impregnated facing offers excellent heat resistance and thermal conductivity, efficiently transferring heat away from the cylinder head
• Conforms to and seals minor surface irregularities, ensuring a reliable seal on imperfect flange surfaces
• High recovery material maintains sealing integrity even if the header or manifold flange loses clamp load
• Can be trimmed to fit modified port applications, providing versatility for custom setups
• Suitable for original equipment replacement as well as high-performance street, drag race, and oval track use

Construction & Design:

The Ultra-Seal gasket features a robust expanded steel core that delivers exceptional strength and stability under high torque conditions. This steel core resists deformation and maintains consistent clamping force, which is critical for preventing exhaust leaks and gasket failure over time. The graphite-faced surface enhances heat resistance and thermal conductivity, allowing heat to dissipate quickly from the cylinder head area. This reduces the risk of gasket degradation caused by excessive heat exposure.

The gasket’s design also allows it to conform to minor surface imperfections on the header or manifold flange, ensuring a tight seal even on older or slightly warped surfaces. Its high recovery material composition means the gasket can rebound and maintain sealing pressure if the flange clamp load decreases, a common issue in high vibration environments like racing.

Installation & Fitment:

The Mr. Gasket Ultra-Seal gasket is designed for straightforward installation as a direct replacement for original equipment gaskets. It fits a wide range of headers and manifolds and can be trimmed if necessary to accommodate modified port sizes or custom applications. This flexibility makes it a versatile choice for both stock and performance exhaust systems. Proper torque specifications should be followed during installation to maximize gasket life and sealing effectiveness.
