VersiSure Shaft Seals


The GenII Seal offers exclusive features that make it the premier shaft seal on the market with the culmination of more than a quarter century of experience in shaft seal design. The Gen II offers a unique ball-bearing drive system that allows the seal ring to “float” and remain in constant contact with the carbon graphite seal surface, resulting in a seal that’s impenetrable to water.

  • The Clamp/Pressure Housing incorporates a unique ball bearing drive system allowing the seal ring to “float” and maintain complete contact with the carbon face of the friction ring.
  • Friction Ring Assembly is constructed of a durable copolymer housing protecting the carbon graphite seal surface.
  • The Gen II houses the stainless steel seal ring and pressure spring securely on the shaft without the use of set screws preventing gailing or damage to the shaft.
  • The Friction Ring Assembly incorporates a water lubricated bearing in the housing to insure proper alignment with the shaft.
  • Available in shaft sizes of 1 1/8” to 5” (30mm to 150mm) in diameter.
  • Dual Water Injection Ports including all necessary hardware.
Gen II


The Dry Seal is a compact economical lip seal designed for quick and easy installation. The lip seal, made specifically for marine use, is in constant contact with the propeller shaft, preventing the water from passing in your vessel. As in all our models, the Dry Seal incorporates a water lubricated alignment bearing in the housing to keep the unit properly aligned with the shaft. There is an optional back-up seal available that can be installed during the original installation, changeable in the future without the need to remove the shaft or unit.

  • Split-face Plate makes it easy to replace inner lip seal without the need for special tools, and with an optional Back-up Seal.
  • Seal Housing constructed of a durable copolymer with built in water lubricated bearing insuring proper alignment of the shaft.
  • Optional Back-up Seal rotates freely on the shaft until replacement is needed.
  • Available in shaft sizes of 3/4” - 8” (20mm - 200mm) in diameter with stern tubes of up to 12” (305mm) in diameter.
