Stephens Gaskets manufactures graphite head gaskets engineered for extreme operating environments where temperature stability, pressure resistance and chemical compatibility are critical.
With decades of specialist gasket manufacturing experience, we supply graphite head gaskets trusted across automotive, industrial and high-performance engine applications.
Graphite remains one of the most reliable sealing materials available. Its unique structure allows it to perform where many other gasket materials fail, making it a preferred choice for demanding engine assemblies.
What Is a Graphite Head Gasket?
A graphite head gasket is a sealing component manufactured from high-purity graphite flake material, often combined with a metallic core or insert.
When compressed between the engine block and cylinder head, the gasket creates a secure seal that:
- Prevents combustion gas leakage
- Maintains oil and coolant separation
- Supports thermal stability under extreme heat
- Compensates for minor flange imperfections
Graphite’s natural ability to conform under pressure makes it exceptionally effective in maintaining long-term sealing performance.
Why Graphite Is Ideal for Head Gasket Applications
Graphite head gaskets are widely used in the automotive and industrial sectors because of their exceptional physical and chemical properties.
Extreme Temperature Resistance
Pure graphite can tolerate temperatures of up to 5000°F in reducing environments, making it ideal for high-heat engine conditions.
High Pressure Performance
Graphite gaskets maintain sealing integrity under intense combustion pressure. Metal-inserted graphite constructions allow operation at even higher pressures.
Excellent Chemical Resistance
Graphite is resistant to a wide range of aggressive chemicals, oils and fluids, reducing the risk of degradation over time.
Low Creep Relaxation
Graphite exhibits very low creep, meaning it maintains clamping force and sealing effectiveness even during prolonged engine operation.
Superior Conformability
Graphite flows into surface imperfections on mating flanges, creating a reliable seal even where surfaces are not perfectly flat.
These properties are why graphite head gaskets remain a trusted solution for both modern and specialist engine builds.
Graphite Grades and Material Options
We manufacture graphite head gaskets using high-grade graphite materials, typically ranging from 95% to 98% carbon content.
This ensures excellent thermal stability, mechanical strength and sealing reliability.
Our graphite gaskets can be supplied with different core and insert options, including:
- Metal foil inserts for added strength and pressure resistance
- Tanged inserts for improved handling and ease of cutting
- Flexible graphite constructions for superior sealing performance
Each configuration is selected based on the specific engine requirements and operating conditions.
