Seals, Valves, and Seats

Send An Enquiry

Polymer components such as seals, valves, and seats exhibit a range of unique properties, making them ideal for a number of end-applications.


All parts are assigned batch numbers with full traceability to the raw material and process parameters. For high volume parts, special gauges and fixtures are employed to ensure 100% inspection before dispatch.

Our typical range of parts includes, but is not limited to:

  • PTFE and PEEK back-up rings
  • Thrust washers
  • Ball-valve seats
  • Butterfly valve seats
  • Piston ring seals
  • Rotary shaft seals
  • Spring-energised seals
  • Lip seals
  • Tapered valves

Given the diversity in automotive and mechanical applications, a number of different polymer part dimensions have been developed – each with its own unique property. When we cross these dimensions with the different polymer grades, we end up with potentially hundreds of designs. Thus, choosing the right component is important and a lot of thought needs to go into the same, before a decision is made.
