FAQs

What types of piston rings do you manufacture?

We manufacture a wide range of piston rings, including compression rings, oil control rings, and special-profile rings for both static and dynamic sealing applications. Our rings are available in various sizes and materials to suit engines, compressors, and hydraulic systems, with bespoke options available for high-performance or legacy equipment.

What types of metallic seals do you manufacture?

We manufacture a variety of metallic seal types, including spring-energised seals, and other specialist configurations. These seals are engineered to provide reliable performance in high-temperature, high-pressure, and corrosive environments where traditional elastomeric seals would fail. We can also develop custom sealing solutions based on your specific application requirements, including variations in geometry, material, and performance characteristics.

What is the size range of products you manufacture?

Our capabilities range from 12mm diameter components to over 2,000mm. Whether you need seals for small hydraulic actuators or large turbine systems, we can manufacture to your exact requirements.

Are your products suitable for both 2-stroke and 4-stroke engines?

Yes, we supply components for both low-speed 2-stroke and medium-speed 4-stroke engines used in industrial settings like diesel locomotives and power generation.

Can your components withstand high temperatures and pressures?

Yes, we produce piston rings and metallic seals designed for extreme operating conditions, including high-temperature valves and nuclear or hydro-electric installations.

What materials and coatings are available for industrial components?

We offer a wide range of materials for industrial applications, including various cast iron grades such as compacted graphite iron, as well as high-performance alloys tailored to your mechanical and thermal requirements. To enhance durability and wear resistance, we also apply advanced coatings such as ceramic chrome plating, plasma spray, and high-velocity oxygen fuel (HVOF) techniques.

Do you offer bespoke component manufacturing?

Absolutely. We specialise in custom-engineered solutions, from prototyping to low and high-volume production. We can work from drawings, samples, or technical specifications.
