Frequently Asked Questions
Q: Is R047004 described as an O-ring or a flat gasket?
A: The catalog identifies it as an O-ring under the sealing-ring product name, not as a flat gasket.
Q: What are its inside diameter, cross-section and material?
A: Those specifications are not provided in the available listing. Confirm the required part reference and any essential dimensional or material requirements before ordering.
Q: Does a similar-product number establish interchangeability?
A: No. The former listing’s similar-product references did not establish replacement compatibility. Use R047004 only where the applicable parts information specifies it.
Q: Can this ring be selected for any fuel, oil or cooling-system seal?
A: No universal fluid or system compatibility is established. Confirm both the intended service location and the specified sealing-ring reference.
Q: What information helps identify the correct seal location?
A: Provide the engine or transmission model and serial number together with the assembly name, diagram reference or location of the ring being replaced.
