PSS Shaft Seal 2" Shaft 3-½" Tube

The PSS Shaft Seal 2" Shaft 3-½" Tube is a marine-grade propeller shaft seal designed to prevent saltwater intrusion and protect your vessel's drive system from corrosion and bearing damage. This seal is essential for inboard and outboard applications where shaft diameters measure 2 inches, acting as a critical barrier against flooding that can lead to costly repairs or catastrophic failure.

Engineered with a fail-safe design principle, the PSS shaft seal utilizes a combination of PTFE and elastomer materials that compress slightly around the shaft as water pressure increases, creating a tighter seal under challenging conditions. Unlike traditional rope or felt seals that degrade over time, this marine-engineered design minimizes maintenance intervals while ensuring exceptional water exclusion.

This seal is particularly beneficial for cruising sailors, commercial fishermen, and offshore operators who cannot afford unexpected bilge water or bearing seizure. Its compatibility with standard hull-through-shaft configurations makes it a reliable choice for various marine environments, including saltwater, brackish, or freshwater.
