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

Bronze-Filled PTFE Seals & Components Available
International Seal supplies bronze-filled PTFE sealing, bearing and engineering components for industrial equipment requiring improved wear resistance and mechanical durability. Components can be manufactured to customer drawings, existing specifications or physical samples, supporting both replacement requirements and repeat production.
Bronze-Filled PTFE Bushes
Bronze-filled PTFE bushes are commonly used in sliding and bearing applications where improved wear resistance and load-bearing performance are required. Components can be machined to specific internal diameters, external diameters, lengths and tolerances to suit industrial equipment.
Bronze-Filled PTFE Bearings
Bronze-filled PTFE bearing components provide low-friction sliding surfaces with improved resistance to deformation under load compared with unfilled PTFE. They are used in suitable mechanical assemblies where operating loads, movement and material compatibility have been considered.
Bronze-Filled PTFE Wear Rings
Bronze-filled PTFE wear rings are used to provide controlled sliding contact and support in suitable mechanical and hydraulic assemblies. The addition of bronze can improve wear performance and dimensional stability, helping support reliable operation under demanding conditions.
Bronze-Filled PTFE Guide Rings
Guide rings manufactured from bronze-filled PTFE can be used to help guide moving components and limit unwanted contact between metallic surfaces. Custom profiles and dimensions can be manufactured to suit specific equipment designs.
Bronze-Filled PTFE Sealing Rings
Bronze-filled PTFE sealing rings can be used in engineered sealing arrangements where improved wear resistance and mechanical support are important. The correct profile and material grade depend on pressure, operating media, temperature and movement.
Custom-Machined Bronze-Filled PTFE Parts
International Seal supports custom bronze-filled PTFE components manufactured to customer drawings or samples, including sleeves, spacers, washers, bearing elements and specialist machined profiles. Requirements can be reviewed for prototypes, replacement components and repeat OEM production.
Custom-Machined Bronze-Filled PTFE Components
International Seal supports the supply of custom-machined bronze-filled PTFE components for industrial sealing, bearing and mechanical engineering applications. Components can be manufactured to customer drawings, existing part numbers, dimensional specifications or physical samples, with material grade and manufacturing requirements reviewed against the application.
Machined components may include:
- Internal & External Diameter Machining
- Precision Turning & Milling
- Custom Sealing Profiles
- Grooves, Steps & Recesses
- Thin-Wall Components
- Bespoke Bushes & Sleeves
- Replacement Sealing Components
- Prototype & Repeat Production Parts
When specifying bronze-filled PTFE components, important considerations include dimensional tolerances, mating surface materials, operating loads, temperature and movement. For repeat requirements, customers can provide annual usage forecasts or scheduled quantities to support production planning and supply arrangements.
Why Choose Bronze-Filled PTFE for Seals & Components?
Bronze-filled PTFE is commonly selected where the low-friction characteristics of PTFE are required alongside improved mechanical performance. The addition of bronze fillers can increase wear resistance, improve resistance to deformation under sustained loading and enhance thermal conductivity compared with virgin PTFE. These characteristics make bronze-filled PTFE particularly useful for bushes, bearings, wear rings and guide components exposed to repeated sliding movement.
However, bronze-filled PTFE does not provide the same broad chemical resistance as virgin PTFE. The bronze filler can be unsuitable for certain corrosive or oxidising environments, and compatibility with the operating media must be reviewed.
International Seal can assist with reviewing the required component design and material specification to identify a suitable sealing or bearing solution.For detailed filler compositions, mechanical properties and material specifications, refer to our Bronze-Filled PTFE Material & Properties Guide.
Bronze-Filled PTFE Seals & Components FAQs
What bronze-filled PTFE components do you supply?
International Seal supplies bronze-filled PTFE bushes, bearings, wear rings, guide rings, sealing rings, washers, spacers and custom-machined components for industrial engineering applications.
Can bronze-filled PTFE components be manufactured to a drawing?
Yes. International Seal can review requirements for bronze-filled PTFE parts manufactured to customer drawings, dimensions, existing specifications or physical samples.
Can you supply bronze-filled PTFE bushes and bearings?
Yes. We can support requirements for custom bushes and bearing components manufactured from suitable bronze-filled PTFE grades.
Are bronze-filled PTFE components suitable for hydraulic applications?
Bronze-filled PTFE is used in suitable hydraulic guiding, bearing and wear applications. Material selection must account for operating pressure, fluid compatibility, temperature and component design.
Can bronze-filled PTFE be used for seals?
Yes. Bronze-filled PTFE can be used in engineered sealing components where the application benefits from improved wear resistance and mechanical characteristics. The correct material grade and sealing design must be selected for the operating conditions.
What is the difference between virgin PTFE and bronze-filled PTFE?
Virgin PTFE provides excellent chemical resistance, electrical insulation and low-friction properties. Bronze-filled PTFE incorporates bronze fillers to improve wear resistance, creep resistance and thermal conductivity, although chemical compatibility may be more limited.
Is bronze-filled PTFE suitable for chemical processing?
Bronze-filled PTFE can be suitable for certain chemical processing environments, but the bronze filler may be affected by corrosive media. Chemical compatibility must be verified against the specific process fluid and operating conditions.
