Abstract: A method for making a press-fit seal which inhibits leak paths between a press-fit joint. An annular metal insert is formed with a cylindrical outer surface. A sealing element is molded to the annular metal insert that includes a main seal lip configured to interface with an outside cylindrical surface of a shaft or hub. Coating material is applied to the cylindrical outer surface of the annular metal insert by either adhering the material to the surface with adhesive or heat shrinking the material to fix to the surface of the annular metal insert to fill-in potential deformities of the cylindrical outer surface of the annular metal insert that could cause a leak path.

Abstract: A cassette seal arrangement for sealing between a shaft and a housing includes a sleeve configured to be mounted to the shaft and including a cylindrical portion and a radially extending portion extending radially outward from the cylindrical portion. A retainer cartridge includes a main retainer configured to be mounted to the housing and supporting a seal member that includes a main seal lip and an exclusionary retainer connected to the main retainer and supporting an exclusionary seal configured to engage the shaft. An electrically conductive non-woven element is disposed longitudinally between the seal member and the exclusionary seal and engages the retainer cartridge and is configured to engage the shaft.

Abstract: A tube seal assembly includes a nipple connected to a first fluid passage and a seal assembly connected to a second fluid passage. The seal assembly includes a cylindrical member attached to the second fluid passage and having a radially extending flange. A seal member includes a metal reinforcement with a cylindrical outer wall and a radially inwardly extending flange at a first end of the cylindrical outer wall. An over-molded seal body includes a locking feature on an interior surface of the cylindrical outer wall that engages the radially extending flange to retain the seal member to the cylindrical member. The over-molded seal body further includes a first sealing lip extending from the radially inwardly extending flange and received against an inner wall of the cylindrical member. An interior surface of the first sealing lip includes a sealing bead engaging the nipple.

Abstract: A shaft-sealing device comprising a sealing ring having a seal secured thereto, and a protective member engaged with the sealing ring. The said protective member includes a cylindrical member having a shaft-engaging surface and a seal-engaging surface, and an annular flange extends radially away from the shaft. The shaft-engaging surface is operable to be attached to the shaft during operation of the device, and the seal-engaging surface is operable to be in sealing contact with the seal during operation of the device. The annular flange is operable to engage the sealing ring.

Abstract: A method of making a dual lip seal is provided including the steps of molding first and second seals to a respective first and second insert. The first and second seals each include a body portion molded to the first and second inserts and including a seal lip extending from the body portion. The body portion of the first and second seals includes a side surface including at least one projection and at least one recess. The at least one projection and the at least one recess of the first and second seals are aligned so that the at least one recess of the first and second seals each receive a corresponding one of the at least one projection of the other of the first and second seals. A heating process is then applied to the first and second seals to bond the seals together via vulcanization.
