Fork Oil Seal for Yamaha R15: Fixed Type
This fork oil seal is built for the Yamaha R15 and supplied to a written specification, so the part that comes off the line in the next order matches the one you approved. Fitment, base material and finish are fixed before sampling starts — that is what keeps the fixed type programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: lead time that slipped twice before bulk started, or packing that arrived crushed at the port. Both are avoidable when the specification is written down before bulk and the approved sample is kept as the reference.

What decides whether it lasts
- Material — Polypropylene is the base; treat any substitution as a new approval.
- Hardness and heat treatment — recorded per lot, not per batch of paperwork.
- Fitment tolerance — checked on the actual Yamaha R15 mounting, not on a catalogue drawing.
- Finish — anodising holds up where the machine sees salt, mud and daily washing.
- Packing — individual packing plus inner cartons sized for the workshop bench.
Processes used on this line
- ultrasonic cleaning
- anodising

Fitment notes
Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.
Where it is used
The fixed type build is the one most often ordered for weekend riding. Riders also fit it for mining sites, farm use, wet weather riding, passenger transport.
Ordering
- Confirm the model year and frame number before ordering.
- Approve a sample made from the actual bulk material.
- Fix the packing and marking at quotation stage.
- Book inspection before the balance payment, not after it.
Questions buyers ask
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
What testing is included?
Standard lots ship with dimensional and hardness reports. ISO/TS 16949 documentation is issued with the shipment when your market requires it.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO/TS 16949-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
