Marine & Power Engines

Precision Polymer Engineering has been at the forefront of Diesel and Gas engine sealing technology for over 20 years. As a leading supplier of high temperatures seals for large bore diesel and gas engines, for both marine propulsion and electricity generation, our engineers understand the pressures manufacturers and operators are under to achieve greater efficiency, fuel economy and extended maintenance intervals, while at the same time reducing emissions.

The combination of superior seal design with high performance elastomer materials ensures that our seals continue to be specified on 2 and 4 stroke engines, both small and large capacity. PPE offers tailored formulations for a wide range of applications, including:

• Liner rings (up to 2000mm diameter)
• Fuel - MDO, HFO, Biofuels and Gas
• HP Injectors
• High temperature exhaust valve seats
• Sump, access covers and rocker covers
• Cylinder joints
• Turbochargers
• Lube oil

Material choice in marine and diesel engine sealing

Elastomers typically offered for this industry include Perlast® Perfluoroelastomers (FFKM), EPDM, NBR, HNBR, fluorocarbons (FKM) and silicone (VMQ). These materials have been developed for long-term resistance to coolants, lubricating oils, corrosion inhibitors and fuels - from high grade diesel and unrefined gases to aggressive heavy fuel oils (HFO).

PPE offers a complete range of engineered solutions for engine sealing requirements including O-rings, D-rings, U-section seals, lip seals, custom profiles and composite parts.
