ABSTRACT:
A lip-type cartridge shaft seal has its toroidal body cavity filled with a silicone rubber adhesive sealant bonded to the main body of the seal. The silicone's adhesive properties and its lower hardness stabilize the body against collapse under intermittent or continuous high pressure forces without interfering with body flexibility.
