PCV Valve for GMC Sierra: Chromed Steel
This pcv valve for the GMC Sierra is specified around chromed steel, 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 a fitment that looked right on paper and failed on the bench, or a fitment that looked right on paper and failed on the bench. Both are specification problems, and both are preventable.

Fitment notes
Confirm the fitment against the VIN or the frame number before ordering; two model years often share a name and not a part.

The specification above is the one most often ordered for mining sites. Related applications include motocross, long-distance touring, security patrols, passenger transport, night riding.
Quality and packing
- In-line inspection with AQL 4.0 sampling on every lot.

- Carton marking and barcode to your specification.
- 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 1000 pieces per line.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
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 9001 documentation is issued with the shipment when your market requires it.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
