Our Graphite Filled PTFE O-Rings are designed for sealing applications requiring low friction, improved wear resistance, chemical resistance, and reliable performance in demanding industrial environments. Manufactured from PTFE reinforced with graphite filler, these sealing rings combine the chemical resistance of PTFE with enhanced mechanical and tribological properties.
Golden Collar can manufacture graphite filled PTFE O-rings in different diameters, cross-sections, filler ratios, and custom configurations according to application requirements.
Key Features
Excellent Chemical Resistance:
Graphite filled PTFE retains good resistance to a wide range of acids, alkalis, solvents, and industrial fluids. Compatibility should be confirmed for specific chemicals and operating conditions.
Low Friction:
The graphite filler helps reduce the coefficient of friction, supporting smoother operation in dynamic sealing applications.
Improved Wear Resistance:
Graphite reinforcement improves wear performance compared with virgin PTFE, making the material suitable for repeated movement and demanding sealing conditions.
Improved Dimensional Stability:
Filled PTFE provides better resistance to deformation and creep under load than unfilled PTFE.
Enhanced Thermal Conductivity:
Graphite filler improves heat dissipation compared with virgin PTFE, which can benefit applications involving friction or elevated temperatures.
Electrical Conductivity:
Graphite-filled grades can provide greater electrical conductivity than virgin PTFE for applications requiring controlled static dissipation or conductive material properties.
Custom Sizes Available:
Inner diameter, cross-section, filler percentage, sealing profile, and other dimensions can be manufactured according to drawings or OEM requirements.
