PSS Shaft Seal 1-¾" Shaft 2-½" Tube

The PSS Shaft Seal 1-¾" Shaft 2-½" Tube is designed to prevent water intrusion at the propeller shaft tunnel, a critical sealing point for various vessels. This component serves as essential protection against saltwater corrosion and internal bilge flooding, making it a vital addition for boaters operating in both saltwater and freshwater environments.

Featuring a dual-stage design, the PSS shaft seal utilizes elastomer bellows and a replaceable cutless bearing contact to accommodate the radial and axial movements of propulsion shafts. This innovative design actively pumps water away from critical bearing surfaces, providing a significant advantage during extended cruising or in rough waters where pressure differentials can vary.

Ideal for mid-size recreational and light-commercial applications, the PSS Shaft Seal fits standard shaft log configurations on vessels ranging from 25 to 50+ feet. Boaters looking to upgrade from aging mechanical seals or outdated packing glands will find this product offers installation flexibility and reduced maintenance requirements.
