PSS Shaft Seal 1" Shaft 1-½" Tube

The PSS Shaft Seal 1" Shaft 1-½" Tube is designed for marine engineers and boat owners who face the challenge of preventing water intrusion where the propeller shaft exits the hull. This seal is crucial for maintaining the integrity of your vessel, as a failing shaft seal can lead to significant issues such as bearing corrosion and transmission damage.

The PSS design utilizes a dynamic, pressure-balanced barrier that effectively stops seawater while allowing normal shaft rotation. It features spring-loaded elastomer components that grip the 1" shaft tightly, and the 1-½" tube houses the assembly against your hull log or shaft tube. This design principle enhances the grip as water pressure builds, reducing the need for frequent adjustments.

Ideal for sailboats, trawlers, cruisers, and working vessels, the PSS Shaft Seal is a reliable choice for those replacing worn rubber hose seals or upgrading from older packing-gland systems. While it offers a robust solution for preventing leaks, some level of maintenance may still be necessary to ensure optimal performance over time.
