PSS Shaft Seal 1" Shaft 2 ¼" Tube

The PSS Shaft Seal 1" Shaft 2 ¼" Tube is designed to prevent water ingress around your propeller shaft, a critical sealing point on any vessel. This product is suitable for various marine applications, including sailboats, trawlers, and performance center-console boats. A failing shaft seal can lead to costly water infiltration, making this product essential for maintaining the integrity of your vessel.

This PSS model accommodates a 1-inch shaft diameter, commonly found on mid-size cruising and fishing boats. It features a unique elastomer bellows design that flexes with hull movement and shaft runout, effectively eliminating leaks associated with older stuffing-box designs. The seal's spring-loaded carbon face rides against a ceramic insert, creating a low-friction barrier that prevents weeping while maintaining minimal drag, which is crucial for fuel economy.

Liveaboards, charter operators, and serious cruisers will find significant benefits in upgrading to PSS technology, especially if they are tired of traditional packing gland maintenance. While installation is generally straightforward, it is advisable to assess compatibility with existing shaft log setups. This model is effective in both freshwater and saltwater environments, providing a reliable solution for various boating needs.
