Fuel Cap for Loncin 150: Heavy Duty
This fuel cap is built for the Loncin 150 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 heavy duty programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: packing that arrived crushed at the port, 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 — Kevlar Composite 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 Loncin 150 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
- laser cutting
- electroplating
- precision stamping
- powder coating
- cold forging
- CNC machining
Fitment notes
Check whether the mounting points on your market version match the catalogue drawing — regional variants are the usual cause of a wrong first order.
Where it is used
The heavy duty build is the one most often ordered for ride-hailing fleets. Riders also fit it for mining sites, ride-hailing fleets, adventure travel, construction sites.
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
What testing is included?
Standard lots ship with dimensional and hardness reports. IATF 16949 documentation is issued with the shipment when your market requires it.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the IATF 16949-compliant build instead of a fresh interpretation.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
