PSS Shaft Seal 1-¾" Shaft 2-¾" Tube

The PSS Shaft Seal 1-¾" Shaft 2-¾" Tube is a crucial component for marine propulsion systems, designed to prevent water intrusion where the drive shaft passes through the hull. This precision-engineered seal is essential for inboard engines, sailboat auxiliaries, and small commercial vessels that require watertight integrity.

Featuring a dual-stage design, the PSS shaft seal incorporates a sacrificial rubber or elastomer bellows that compresses against the shaft, along with a hard carbon face seal that maintains contact even under deflection and vibration. This design philosophy emphasizes reliability and efficiency, ensuring that the seal performs effectively without excessive drag that could affect fuel economy.

Users can expect the PSS shaft seal to operate effectively for several years, with typical service life influenced by usage conditions. Once properly installed and aligned, this seal runs quietly and efficiently, making it an excellent choice for both retrofit and original equipment installations.
