What Is a Head Gasket?
The head gasket forms a seal between the cylinder head and engine block. Its primary role is to contain combustion pressures while preventing coolant and lubricating oil from mixing or escaping.
A properly manufactured head gasket must withstand:
- High temperatures
- Extreme pressure cycles
- Chemical exposure
- Thermal expansion
- Vibration and movement
Because of these demanding operating conditions, material selection is critical to long-term reliability and performance.
Head Gasket Materials
Selecting the correct material depends on the application, operating temperatures, pressures and engine design.
Graphite Head Gaskets
Graphite remains one of the most popular head gasket materials due to its excellent sealing properties and resistance to high temperatures.
Benefits include:
- Excellent conformability
- Good thermal resistance
- Reliable sealing performance
- Suitable for many OEM applications
Graphite materials are commonly used in automotive and industrial engine applications where consistent sealing performance is required.
Multi Layer Steel (MLS) Head Gaskets
MLS head gaskets are widely used in modern engines due to their ability to withstand high combustion pressures.
Advantages include:
- Exceptional durability
- High pressure resistance
- Excellent recovery characteristics
- Suitable for turbocharged and performance engines
MLS gaskets are often specified by OEM manufacturers and motorsport engineers.
Copper Head Gaskets
Copper head gaskets are widely used in high-performance and specialist engine applications.
Benefits include:
- Excellent heat transfer
- High temperature capability
- Superior durability
- Ideal for performance engines
Copper head gaskets are particularly popular within motorsport and classic vehicle restoration projects.
Composite Head Gaskets
Composite materials continue to offer a practical solution for many engine designs.
Advantages include:
- Cost-effective performance
- Reliable sealing
- Good compressibility
- Suitable for a variety of engine configurations
Composite head gaskets remain widely used in restoration projects and lower-volume applications.
Signs of Head Gasket Failure
A damaged head gasket can lead to significant engine problems if left unresolved.
Common symptoms include:
- Loss of engine power
- Engine overheating
- White exhaust smoke
- Coolant loss
- Oil contamination
- Excessive pressure in the cooling system
- Poor engine performance
While Stephens Gaskets does not provide repair services, we manufacture replacement head gaskets to help engineering businesses and restoration specialists return equipment to service.

Frequently Asked Questions
What does a head gasket do?
A head gasket seals the joint between the cylinder head and engine block, preventing the escape of combustion gases while keeping coolant and oil separated. This allows the engine to operate efficiently and maintain compression.
What causes head gasket failure?
Head gasket failure can occur due to overheating, excessive pressure, poor installation, material degradation or engine component movement. The exact cause often depends on operating conditions and engine design.
Can you manufacture a head gasket from a sample?
Yes. Stephens Gaskets can manufacture replacement head gaskets from an existing sample, technical drawing or CAD file. This service is particularly valuable for obsolete or discontinued engine components.
What materials are used for head gaskets?
Common materials include graphite, multi-layer steel (MLS), copper and composite materials. The most suitable material depends on the operating temperature, pressure and application requirements.
Do you manufacture head gaskets for classic vehicles?
Yes. We regularly produce bespoke head gaskets for classic cars, motorcycles, agricultural machinery and heritage equipment where original parts are no longer available.
Are MLS head gaskets better than composite gaskets?
MLS head gaskets generally provide greater durability and pressure resistance, making them suitable for modern and performance engines. Composite gaskets remain an effective solution for many traditional applications.
Can you supply prototype quantities?
Yes. We support prototype development, one-off components, low-volume production and larger manufacturing runs depending on project requirements.
Do you manufacture head gaskets in the UK?
Yes. Stephens Gaskets manufactures custom head gaskets in the UK and supplies customers across a wide range of engineering and industrial sectors.
