Marine Sealing Solutions
High-performance sealing solutions, designed for durability and performance for the demanding environments of the marine industry.
Whether you're dealing with commercial vessels, leisure boats, offshore rigs, or marine equipment, our seals are built to ensure optimal performance, reliability, and safety. We understand the unique challenges of the marine environment and provide seals that stand up to saltwater exposure, high pressures, temperature extremes, and continuous motion.
Reliable seals for safety in the marine industry
Our sealing solutions are engineered to withstand the harshest conditions, ensuring your vessels, equipment, and systems remain fully operational in both calm seas and turbulent waters. From shipbuilding to offshore oil rigs, we offer a comprehensive range of seals that meet the strictest standards for performance and longevity.
Case Study
Description
ROV Hydraulic Actuator
A leading ROV manufacturer approached us with a sealing issue in one of their hydraulic cylinders. They were experiencing leakage at low pressures, but the seal also needed to withstand high pressures of up to 230 bar.
We provided a tailored, fast, and effective sealing solution within 7 days.
How our seals improve performance in marine applications
- Prevent Leaks: Minimise risk of water, fuel, and oil leaks, ensuring the safety and efficiency of critical systems.
- Enhance Equipment Lifespan: By providing superior protection against corrosion and wear, our seals extend the life of your machinery and equipment.
- Reduce Maintenance: Reliable seals reduce the need for frequent repairs and downtime, improving the overall operational efficiency of your fleet or platform.
- Ensure Safety: By preventing the ingress of water, contaminants, or gases, our seals play a crucial role in safeguarding both the crew and the environment.
Marine Sealing Products
Designed for static and dynamic applications, our O-rings provide a tight seal in environments exposed to saltwater, oils, and extreme pressure. These seals are available in a variety of elastomers, including nitrile, silicone, and fluorocarbon, to ensure compatibility with your specific marine environment.
Our gaskets are engineered to provide leak-proof seals in demanding marine environments. From engine compartments to pipe flanges, our gaskets ensure that components remain secure, preventing leaks and enhancing system efficiency.
Essential for rotating parts, our rotary seals are built to prevent contamination and leakage in rotating machinery such as pumps, motors, and shafts. With enhanced resistance to seawater, chemicals, and high-speed operations, our rotary seals deliver exceptional reliability for marine engines, hydraulic systems, and other critical components.
Prevent leakage and protect vital systems in boats, vessels, and marine machinery with our robust shaft seals. Designed to withstand the high pressures and motion of marine environments, these seals ensure continuous operation without compromising performance.
Hydraulic systems are essential for the operation of heavy-duty marine equipment. Our hydraulic seals are engineered to prevent leaks and maintain performance under high pressure, ensuring your machinery operates smoothly and efficiently, even in the harshest marine conditions.
Widely used in marine applications, especially for sealing rotating or reciprocating shafts that pass through a housing or stuffing box - most commonly in propeller shafts, rudder stocks, deck machinery, and pumps.
Because no two marine systems are the same. Our team works closely with OEMs and marine engineers to design and manufacture custom seals that meet your unique specifications. Whether for new construction, retrofits, or repairs, our custom seals ensure a perfect fit and superior performance.
Marine Sealing Materials
Nitrile (NBR): Good for fuel and oil resistance.
EPDM: Excellent for water and steam; UV and ozone resistant.
Viton™ (FKM): Excellent chemical resistance, suitable for high temperatures.
Silicone: UV and temperature resistant; used in low-pressure or static applications.
PTFE (Polytetrafluoroethylene): Chemically inert, non-reactive, excellent for corrosive environments.
Graphite: High temperature and chemical resistance.
Polyurethane (PU): High wear and abrasion resistance.
Metal: Stainless steel, copper, or Inconel used in high-pressure, high-temperature sealing
