Overview

Seal a boat's 1-1/2-inch propeller shaft with this PSS Shaft Seal, sized for stern tubes from 2-1/2 to 2-5/8 inches in diameter. A rotating stainless steel rotor meets a stationary carbon flange to form the mechanical face seal, helping keep water out of the bilge.

Key features

  • A mechanical face seal avoids the ongoing adjustment associated with traditional packing glands.
  • Preloaded bellows keep the sealing faces in contact while accommodating propeller thrust.
  • The carbon flange floats around the shaft to accommodate most misalignment and vibration.
  • Two recessed O-rings seal the rotor to the shaft and rotate with it, avoiding wear during operation.
  • Retrofit suitability allows installation as a replacement for an existing shaft seal.
