Carbon-Filled PTFE Seals & Machined Components
International Seal supplies carbon-filled PTFE seals and precision-machined components for industrial applications requiring improved wear resistance, mechanical durability and resistance to deformation under load compared with virgin PTFE. Our range includes carbon-filled PTFE sealing rings, back-up rings, bushes, bearings, wear rings, guide rings and custom-engineered components manufactured to customer drawings, samples or existing specifications.
Carbon-filled PTFE combines the low-friction characteristics of Polytetrafluoroethylene (PTFE) with the mechanical benefits of carbon fillers. It is commonly selected for industrial sealing and engineering applications involving sliding movement, repeated operation and mechanical loading where unfilled PTFE may not provide sufficient wear or creep resistance.
International Seal supplies carbon-filled PTFE components to distributors, OEMs and industrial customers throughout the UK and internationally, supporting prototype requirements, replacement components and repeat production volumes.

- Prototype & Repeat Production Parts
When specifying carbon-filled PTFE components, important considerations include dimensional tolerances, mating surface finish, operating temperature, pressure, mechanical loading and movement. The selected carbon-filled compound should also be reviewed for chemical compatibility with the process media and suitability for the mating materials.
For repeat requirements, customers can provide annual usage forecasts or scheduled quantities to support production planning and supply arrangements.
Why Choose Carbon-Filled PTFE for Seals & Components?
Carbon-filled PTFE is commonly selected where the low-friction characteristics of PTFE are required alongside improved wear resistance and mechanical performance. The addition of carbon fillers can reduce creep and deformation under sustained loading while improving wear performance compared with virgin PTFE. These characteristics make suitable carbon-filled PTFE grades useful for sealing rings, bushes, bearings, wear rings and guiding components exposed to repeated movement.
Carbon-filled PTFE may also provide improved thermal characteristics, although the extent of these benefits depends on the filler type and compound formulation. International Seal can assist with reviewing the required component design and material specification to identify a suitable sealing or engineering solution.
