OEM ODM Custom Rubber Rings PTFE Chemical Resistant
Custom PTFE O-Rings for Specified Chemical and Static Sealing Duty
PTFE Ring Selection: Confirm Construction Before Chemical-Service Approval
Confirm whether the required part is a solid PTFE ring, a filled PTFE ring or a fluoropolymer-encapsulated elastomer ring. These constructions have different fit and installation requirements.
| Order detail | Information required |
|---|---|
| Grade and construction | PTFE grade, filler if any, and solid or encapsulated construction. |
| Dimensions | ID, cross-section, units and tolerances or exact standard size reference. |
| Chemical exposure | Fluid, concentration, temperature and exposure duration. |
| Joint design | Groove dimensions, static face or flange arrangement and assembly constraints. |
| Pressure duty | Pressure cycle, clearance and support details for the complete seal design. |
Solid PTFE has low elasticity and can deform under sustained load. Do not assume it can stretch into the same groove or replace an elastomer O-ring directly. Confirm installation and dimensional acceptance with the equipment drawing; pressure and temperature capability belong to the specified sealing arrangement.
Product Description
PTFE O-rings are circular-section thermoplastic sealing rings. PTFE is not rubber and has limited elastic recovery, so the groove, assembly method and service conditions need a PTFE-specific design review.
Potential applications below require the correct PTFE grade, geometry and equipment approval:
1.Pipe Connection
2.Medical equipment enquiries with application-specific documentation
3.Automotive Repair
4.Hydraulic equipment with a specifically designed PTFE sealing arrangement
5.Industrial machinery static joints
6.Valve Connection
Shanghai Qinuo Industry supplies sealing rings to agreed size and material specifications. For PTFE rings, give the exact AS568 or ISO 3601 size reference, or a dimensioned custom drawing, and identify whether solid PTFE, a filled grade or an encapsulated construction is required. Special medical or other conformity requirements must be stated and supported for the actual supplied grade.
