Extended Product Information

FAQs

What material is the Elring Seal Ring (406.350) made from?

The seal ring is made from EPDM (Ethylene Propylene Diene Monomer) rubber, known for its good resistance to weathering, ozone, and heat.

What are the exact dimensions of this seal ring?

The seal ring has an inner diameter of 30mm, an outer diameter of 40mm, and a thickness of 5mm.

How many seal rings are included in one pack?

Each pack contains 25 seal rings.

How do I know if this seal ring will fit my vehicle?

You should verify your vehicle's specific part numbers against the OEM Cross References listed in the product information. Also, confirm that the physical dimensions (30x40x5mm) match the requirements of the component you are servicing.

Can this seal ring be used for high-temperature applications?

EPDM rubber generally offers good heat resistance, but its suitability depends on the specific temperature range of your application. Consult technical specifications for operating limits.

What is the cross-sectional form of this seal?

The cross-sectional form is an O-Ring.

Where should I store unused seal rings?

Unused seal rings should be stored in their original packaging in a cool, dry place, away from direct sunlight and potential sources of ozone.

Troubleshooting

Seal is difficult to install or appears pinched.

Ensure the mating surfaces and the seal itself are adequately lubricated. Check that the seal is seated correctly in its groove and is not twisted. Verify the dimensions are correct for the application.

Leak occurs after installation.

Re-check that the seal was installed correctly and is not damaged. Inspect the mating surfaces for flatness and cleanliness. Confirm the seal's dimensions and material are appropriate for the fluid and pressure involved.

Seal appears to be degrading prematurely.

Ensure the seal is not exposed to incompatible chemicals, excessive heat, or ozone. Verify that the EPDM material is suitable for the operating environment.

Setup, Compatibility & Care

Setup:

  1. Verify Fitment: Before installation, meticulously check that the vehicle's original part number matches one of the OEM cross-references provided, and confirm the dimensions (30mm inner diameter, 40mm outer diameter, 5mm thickness) are correct for the intended application.
  2. Clean Surfaces: Ensure the mating surfaces where the seal will be placed are clean, dry, and free of debris, old gasket material, or corrosion.
  3. Lubricate: Apply a small amount of compatible lubricant (e.g., silicone grease or petroleum jelly) to the seal and the groove or surface it will sit in. This aids installation and prevents damage during fitting.
  4. Install Seal: Carefully place the O-ring into its designated groove or position. Ensure it is seated correctly and not twisted or pinched.
  5. Assemble Component: Reassemble the part containing the seal, ensuring even pressure is applied during tightening, if applicable, to avoid deforming the seal.
