Cork gaskets remain a highly effective sealing solution where compressibility, resilience, and long-term leakage prevention are required. At Stephens Gaskets, we are experienced UK cork gasket suppliers, manufacturing precision cork and nitrile-bonded cork gaskets for industrial, commercial, and specialist applications.
With over 70 years of gasket manufacturing expertise, we supply cork gaskets that deliver reliable sealing performance, consistent quality, and excellent value across a wide range of operating conditions.
What Are Cork Gaskets?
Cork gaskets are typically manufactured from nitrile-bonded cork, combining natural cork granules with nitrile rubber. This structure creates a gasket material that is both compressible and resilient, allowing it to conform to surface irregularities while maintaining a reliable seal.
The addition of nitrile rubber improves flexibility, durability, and resistance to oils and fuels, making cork gaskets suitable for demanding sealing applications.
Advantages of Nitrile-Bonded Cork Gaskets
Nitrile-bonded cork is widely specified because it offers a strong balance of performance and cost efficiency.
Key benefits include:
- Excellent compressibility for low and high bolt loads
- Good flexibility and recovery after compression
- Resistance to oils, fuels, and many fluids
- Operating temperature range typically from -20°C to +120°C
- Effective vibration damping and noise reduction
These properties make cork gaskets a reliable, general-purpose sealing solution across many industries.
What Are Cork Gaskets Used For?
Cork gaskets are used in a wide variety of sealing and vibration control applications.
Common uses include:
- Valve covers and crankcase covers
- Oil sumps and fuel system components
- Electrical switchgear and enclosures
- Door seals and access panels
- Anti-vibration and cushioning applications
Because cork gaskets provide long-term leakage prevention, they are often chosen for applications where maintenance access is limited or downtime must be minimised.
