The sealing ring is made from FPM (fluoride rubber), known for its excellent resistance to heat, oils, fuels, and various chemicals.
This sealing ring has an inner diameter of 9.2 mm and a thickness of 1.8 mm. Its cross-sectional form is an O-Ring.
Each pack contains 25 sealing rings.
Yes, FPM material generally offers good resistance to high temperatures, making it suitable for many demanding applications.
Verify that the required inner diameter (9.2 mm) and thickness (1.8 mm) match your application. You can also check the provided OEM cross-reference numbers against your equipment's specifications.
The OEM cross-reference numbers (e.g., AUDI: N 900 396 03) indicate equivalent part numbers from other manufacturers, helping you confirm compatibility with specific vehicle or machinery models.
It is recommended to store them in a cool, dry place, away from direct sunlight, heat sources, and potential chemical contamination to maintain their material integrity.
Ensure the sealing groove and the seal itself are adequately lubricated with a compatible lubricant. Check that the correct seal size is being used and that no debris is obstructing the installation path. Do not force the seal; seating it evenly is key.
Verify that the seal was installed correctly without twisting or damage. Check that the mating surfaces are clean, flat, and free of defects. Ensure the correct seal part number for the application was used and that the component's pressure and temperature ratings are within the seal's capabilities.
Confirm that the fluid or environment the seal is exposed to is compatible with FPM (fluoride rubber) material. Extreme temperatures or aggressive chemicals beyond the material's rating can cause premature degradation. Re-check application suitability.
Setup: Ensure the sealing surfaces are clean, dry, and free from burrs or damage before installation. Lightly lubricate the seal with a compatible lubricant if recommended by the equipment manufacturer. Carefully slide the seal into its designated groove, ensuring it is seated evenly and without twisting. Avoid using excessive force.
Compatibility: This sealing ring is specifically designed with an inner diameter of 9.2 mm and a thickness of 1.8 mm. Verify these dimensions match the requirements of your application. Consult the OEM cross-reference list (AUDI: N 900 396 03, BMW: 1 742 635, etc.) to confirm compatibility with your specific vehicle or equipment model. It is crucial to match the part number precisely.
Care: Store the sealing rings in a cool, dry place away from direct sunlight and extreme temperatures. Avoid contact with incompatible chemicals that could degrade the FPM material. Inspect seals before installation for any signs of damage.
