PSS Shaft Seal 2-½" Shaft 3-½" Tube

The PSS Shaft Seal 2-½" Shaft 3-½" Tube is an essential component for marine vessels, designed to protect the drive shaft from water intrusion and corrosion. This product is particularly beneficial for boat owners who rely on through-hull shaft penetrations, ensuring reliability during extended cruising and heavy-use seasons.

Engineered with a dual-chamber construction, the PSS Shaft Seal features a primary seal chamber that effectively prevents water migration, along with a secondary weep hole that allows for controlled drainage of any unavoidable seepage. Made from marine-grade elastomers and corrosion-resistant hardware, this seal is built to endure the harsh conditions of saltwater environments, high RPM operations, and temperature fluctuations.

Ideal for owners of sailboats, trawlers, and displacement-hull powerboats, the PSS Shaft Seal ensures that shaft-driven propulsion systems operate smoothly and efficiently. Installation is straightforward for vessels already equipped with a through-hull shaft, making it a practical choice for maintenance and upgrades.
