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
- 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).

Products for Engines
Below is a selection of the most common products we supply for use in Marine and Power Engines. Visit the Products page to see the full range.
With a specialist elastomer for every sealing application, our engineers can identify an elastomer O-ring to perform perfectly in your operating environment.
Large Diameter O-rings & Seals
Fully molded, high quality, large diameter O-rings manufactured in sizes up to 2.5 metres (8ft) outer diameter, with no joined or spliced ends.
D-rings prevent twisting, rolling and spiral failure often seen when O-rings are used in reciprocating applications; available in standard O-ring sizes and custom sizes.
Energized lip seals provide a versatile sealing system for uni-directional pressure applications in either static or reciprocating dynamic conditions, in rod or piston grooves.
