Abstract
A multi-layer radial lip seal assembly adapted to be retained to the housing of an automotive air conditioning compressor and to be disposed about a rotatable shaft extending through a chamber provided in the housing. The lip seal assembly includes a first seal member or disc of virgin FEP adjacent to a second seal member or disc of graphite-filled PTFE. A retainer is provided to support the first and second seal members and an elastomer is molded to the retainer and seals the seal members to the retainer. The first seal member acts to protect the second seal member during installation and quickly wears away, so that the second seal member becomes the primary seal member.
