Expansion Valve for Jeep Wrangler: Polypropylene
This expansion valve for the Jeep Wrangler is specified around polypropylene, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is inconsistent hardness between lots, or lead time that slipped twice before bulk started. Both are specification problems, and both are preventable.

The specification above is the one most often ordered for food delivery. Related applications include night riding, ride-hailing fleets, delivery fleets, adventure travel, coastal delivery.
Quality and packing
- In-line inspection with AQL 2.5 sampling on every lot.

- Golden sample retained at the factory as the reorder reference.
Questions buyers ask
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
What is the minimum order quantity?
The standard MOQ is 3000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
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.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
