Why choose PPE?

We manufacture engine sealing components for:

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

Lubrication oil

PPE seals are specified on 2 and 4 stroke engines, both small and large capacity.

Engine sealing benefits

PPE’s specialist sealing engineers understand the pressures manufacturers and operators are under in the marine, diesel and power-gen sectors, to generate better performance and achieve the best possible equipment reliability. Our innovative elastomer sealing materials and products are developed with these demands in mind.

Reliability

Seal failure in marine and power engines can have catastrophic results. PPE’s range of high performance elastomers have been engineered to deliver long-term resistance to specific challenges found in engine sealing.

Efficiency and economy

When seals within an engine are effective, less energy is wasted – which allows the engine to achieve better fuel economy. PPE sealing components are designed to prevent engine wear and tear, and reduce friction to translate fuel into motion more efficiently.
