At Stephens Gaskets, we specialise in providing premium marine gaskets that meet the rigorous demands of the maritime and offshore industries. The harsh marine environment exposes equipment to saltwater, extreme weather, vibration, and pressure changes, making high-quality gaskets essential for safety and efficiency.
Our marine gaskets are engineered to provide watertight and airtight seals, protecting vessels, offshore structures, and marine machinery from leaks, corrosion, and mechanical failures.
What Are Marine Gaskets?
Marine gaskets are specialised sealing components designed to prevent water ingress, contamination, and leaks in ships, offshore platforms, and marine equipment.
They create secure seals between surfaces, ensuring protection against external elements and maintaining system efficiency.
These gaskets are used in a range of applications, from shipbuilding to marine HVAC systems, ensuring the reliability and safety of marine operations.

Materials Used in Marine Gaskets
At Stephens Gaskets, we manufacture marine gaskets from premium materials designed to withstand extreme maritime conditions.
1. Neoprene
- Excellent saltwater resistance, making it ideal for exterior sealing.
- UV and ozone-resistant, ensuring long-term durability.
2. EPDM (Ethylene Propylene Diene Monomer)
- Superior weathering and ozone resistance, perfect for marine HVAC applications.
- High temperature resistance, maintaining flexibility in extreme conditions.
3. Silicone Rubber
- Performs in high-temperature environments, ideal for engine and exhaust systems.
- Highly flexible and resistant to chemical exposure.
4. Nitrile Rubber (Buna-N)
- Exceptional oil and fuel resistance, making it suitable for fuel tanks and pipelines.
- Provides strong mechanical performance under pressure.
5. PTFE (Polytetrafluoroethylene)
- Highly chemical-resistant, suitable for aggressive marine environments.
- Low friction properties, ensuring longevity and performance.
6. Cork-Rubber Composites
- Combines flexibility and compressibility, ideal for machinery and vibration-damping seals.
- Provides excellent sealing properties under low pressure.
Common Challenges in Marine Sealing and How We Solve Them
1. Leakage and Water Intrusion
- Poor-quality gaskets can fail under pressure, leading to leaks in vessel compartments and equipment.
- Our gaskets are precision-engineered for airtight and watertight sealing.
2. Corrosion and Material Degradation
- Constant exposure to saltwater and UV rays can cause gasket deterioration.
- We use marine-grade materials resistant to environmental stressors.
3. High Vibrations and Pressure Changes
- Engine and mechanical movement can cause gasket displacement and wear.
- Our flexible yet durable gaskets withstand mechanical stress and remain intact.
4. Difficult Customisation and Fit
- Standard gaskets may not fit complex or irregular shapes in marine systems.
- We provide custom gasket solutions tailored to exact specifications.
