PSS Shaft Seal 1-3/8" Shaft 2-1/4" Tube

The PSS Shaft Seal 1-3/8" Shaft 2-1/4" Tube is a marine-grade propeller shaft seal designed to prevent water intrusion at the stuffing box, a critical vulnerability for vessels with a through-hull drive system. This product is essential for center consoles, sport cruisers, and working boats, as it helps avoid bilge contamination, corrosion, and potential flooding in the engine room.

Engineered with elastomer stripper rings and a precision-machined tube, the PSS seal establishes a dynamic seal around rotating shafts while allowing controlled lubrication flow. The 1-3/8" shaft diameter is suitable for mid-range inboards and many auxiliary drive installations, while the 2-1/4" tube dimension fits standard stuffing box bore openings found on fiberglass and composite hulls. This cartridge-style seal is designed to withstand harsh marine environments, providing consistent performance over time.

Commercial operators, cruising sailors, and offshore fishermen benefit from the reliability of PSS seals, which eliminate the need for frequent packing maintenance. The straightforward installation process is ideal for tight engine compartments, ensuring that your vessel's core systems remain protected and operational. With this seal, you can confidently navigate various marine environments without the worry of water intrusion.
