Product Specifications and Technical Details

The PSS Shaft Seal is designed for shaft sizes ranging from 3/4" (20mm) to 6" (150mm), making it versatile for a wide range of marine applications. This specific model features a 45mm shaft size and a 2.750" to 2.875" stern tube diameter, ensuring a perfect fit for your vessel. The seal operates by creating a mechanical face seal between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange. This design allows for 100% water tightness, eliminating water in the bilge and reducing wear on the propeller shaft. The carbon flange is bored larger than the shaft diameter, allowing it to "float" around the shaft and compensate for misalignment and vibration issues.

• Shaft Size Range: Suitable for shaft sizes from 3/4" (20mm) to 6" (150mm), offering flexibility for various applications.
• Material Quality: Made with high-quality stainless steel and carbon, ensuring long-lasting durability and resistance to corrosion.
