Drier Bottle for Great Wall Poer: EPDM Rubber
This drier bottle for the Great Wall Poer is specified around epdm rubber, 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 warranty claims traced back to a single lot, or packing that arrived crushed at the port. Both are specification problems, and both are preventable.
