55mm Shaft / 2 1/2in Tub PSS Shaft Seal

The PSS Shaft Seal is a cutting-edge marine mechanical seal designed for durability and efficiency. This premium product is the number one selling marine mechanical seal worldwide, trusted by many reputable boat builders and yards. Its innovative design ensures a 100% watertight seal, eliminating the need for constant maintenance and adjustments typically associated with traditional packing type glands.

Product Specifications

The PSS Shaft Seal is specifically designed for shaft sizes ranging from 3/4" (20mm) to 6" (155mm), making it versatile for various boat applications. This particular model is tailored for a 55mm shaft and a 2.500"- 2.625" stern tube diameter. The seal features a mechanical face seal created between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange. This design allows for excellent alignment and vibration compensation, ensuring optimal performance and longevity. The carbon flange is bored larger than the shaft diameter, allowing it to "float" around the shaft and compensate for misalignment and vibration issues.
