PSS Shaft Seal 2-½" Shaft 4" Tube

The PSS Shaft Seal 2-½" Shaft 4" Tube is a precision marine propulsion component designed to prevent water intrusion where your drive shaft exits the hull. This product is ideal for cruisers, sportfishers, and displacement trawlers, serving as a vital component for maintaining engine longevity by stopping saltwater and debris from reaching sensitive areas.

Engineered with a dynamic lip design and elastomer technology, this PSS model creates a watertight barrier under rotating shaft loads while minimizing friction and heat generation. Its construction is robust enough to withstand the thermal cycling and pressure variations typical in saltwater and brackish environments, ensuring reliable performance.

Marine mechanics and captains prefer PSS seals for replacing worn stuffing boxes, particularly on vessels that experience water pooling around the shaft log. The compact design and weight facilitate straightforward installation during haul-outs or new builds, making it a favored choice among professionals in the marine industry.
