The Operation of Elastomeric Radial Lip Seals at High Temperatures 750810

The evolution of the modern elastomeric radial lip seal parallels the evolution of the automobile. Higher operating temperatures in modern automotive applications are approaching the limits of present seal designs and materials.
Seal ultimate life depends upon the ability of the seal design and material to resist heat. At elevated temperatures, seals may become hard and brittle, blister, crack, and degrade. High wear may also result.
Improvement of seal performance at elevated sump temperatures can be obtained with modern seal design and materials.
