Full Description

Purpose/Material Description.

This standard covers the requirements of expanded elastomeric rubber seals attached to a solid carrier used in sealing body openings.

Material Description.

The bulb or sealing portion of the weatherstrips shall be made from dense or expanded closed-cell Ethylene Propylene Diene Monomer (EPDM) rubber. For attachment purposes, weatherstrips require a dense base (carrier). This carrier shall be coextruded or co-molded with the sealing portion. The carrier shall incorporate a metal insert if specified on the respective part drawing. The specifications for the dense base and the metal carrier shall be specified on the engineering part drawing or in the math data file.

Weatherstrip assemblies shall consist of continuous extruded sections or sections joined together. These sections shall be joined by either transfer or injection molded corners, or mitered corners securely attached with suitable adhesive. Joint and corner offset criteria per GMW18606.

Coatings.

When applied, coatings shall be non-abrasive and uniform in color, finish, and texture. Coatings shall meet the requirements of color and gloss as established by GM Appearance Engineering.

Symbols.

Not applicable.

Applicability.

Typical applications include sealing profiles in the body area, e.g., on doors, hoods, liftgates, trunks, and front storage compartments (“frunks”).

Remarks.

None.
