PSS PRO Shaft Seal 1-1/2" Shaft & 2-1/2" Tube

The PSS PRO Shaft Seal 1-1/2" Shaft & 2-1/2" Tube is designed for marine engineers tackling the challenge of water intrusion around propeller shafts. This precision-engineered seal assembly is essential for maintaining a watertight barrier, ensuring that your engine compartment remains dry and free from water damage. It's particularly useful for those operating cruisers, sportfishers, or displacement hulls, where reliable performance is critical.

The PSS PRO design features a 1-1/2" diameter shaft and a 2-1/2" tube, making it compatible with many standard inboard installations. Its dual-stage design incorporates a primary elastomer barrier and a secondary water shield, providing enhanced reliability even in harsh saltwater environments. The elastomeric spring-loaded components ensure low-friction contact with the rotating shaft, effectively sealing out water without causing binding or dragging.

This assembly is ideal for both retrofit and replacement applications, offering a solution that extends service life significantly compared to older designs. Users can expect improved performance, as PSS seals naturally shed salt deposits and resist degradation from fuel and oil exposure. This makes the PSS PRO Shaft Seal a dependable choice for maintaining the integrity of your marine vessel.
