PSS Shaft Seal 1-½" Shaft 2-¾" Tube

The PSS Shaft Seal 1-½" Shaft 2-¾" Tube is a specialized marine mechanical seal designed specifically for inboard propulsion systems. This seal is essential for preventing water intrusion at the propeller shaft, a critical area where water can enter the bilge and engine compartment, especially in saltwater environments.

Engineered with a compression-style design, the PSS seal grips the 1-½" shaft with a 2-¾" outer tube diameter, creating a reliable watertight barrier. It utilizes resilient elastomer rings that flex under pressure, accommodating minor shaft run-out and vibrations from engine torque and wake impact, ensuring durability without the need for frequent adjustments.

Owners of inboard cruisers, fishing boats, and trawlers will find this seal particularly beneficial, especially those operating in saltwater where corrosion is a concern. Its passive design, with no moving parts, is crucial for reliability when service options are limited, making it an ideal choice for serious boaters.
