LASDROP SHAFT SEALS 2-1/2" Gen II Shaft Seals

The Gen II offers exclusive features that make it the premier shaft seal on the market. 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. The result is a seal that's impenetrable to water.

The Gen II uses a 316-marine grade stainless steel spring to provide pressure to the seal surfaces. Together, the spring and seal ring rotate along with the shaft, and remain secured in the Clamp/Pressure housing. Because there's virtually no metal-to-metal contact, you eliminate the risk of electrolysis.

The Gen II is available for shaft sizes 1" - 4," accommodating stern tube sizes of up to 8" OD.

  • The Friction Ring assembly is mounted with a rigid connection hose and uses a carbon graphite sealing surface all encased by a durable copolymer housing.
  • Built into the friction ring assembly is a cutlass bearing to ensure proper and constant alignment to the shaft.
  • The Clamp/Pressure Assembly secures the assembly around the shaft, preventing the galling or damage to the shaft that can occur with setscrews.
  • The 316 stainless steel seal ring floats on a ball bearing drive system, maintaining complete contact with the carbon graphite seal surface.
  • Solid brass hose barbs.
  • AWAB hose clamps are 316 stainless steel, manufactured with indentations rather than perforations, providing twice the tensile strength and eliminating friction as in regular clamps.
