Can an OE number alone confirm an oil seal replacement?

Use the OE number to find candidate parts, then compare dimensions, profile, material requirements and application position against the original drawing or verified sample. Obtain written confirmation of any differences.

Information to compare

• OE number
• existing seal markings
• full dimensions
• profile drawing
• material
• equipment model and position

Resolve the reference into an approved specification

Send the complete reference including suffixes, source catalogue, equipment model and photographs of markings. Include measured dimensions or an approved drawing when available.

Ask for a side-by-side comparison of the offered part’s dimensions, lip arrangement, material, rotation features and installation requirements. Record each difference and who will approve it.

For incomplete or conflicting references, request a sample review before production approval. Keep the approved drawing revision and supplier part number on the purchase order for repeat orders.

Certification, parameters and delivery

Ask for current certificates relevant to the manufacturing site and your purchasing requirements. Verify the document number, scope and validity. Match inspection records to the part and lot specified in your order.

State the dimensions, compound requirements and operating conditions you need confirmed. Request separate sample and production schedules, including the approval trigger, dispatch date and destination. VKEFOT certification availability, MOQ and delivery dates must be confirmed in the quotation for your selected part.
