Introducing the PSS 2in Shaft / 4in Tube Shaft Seal, a premium marine mechanical seal designed for maximum performance and durability. This top-selling product is widely recognized as the leading marine mechanical seal worldwide, trusted by many reputable boat builders and yards. The PSS Shaft Seal is not only installed as standard equipment but also serves as the premier retrofit solution on the global market.
  • Sealing Efficiency: The PSS Shaft Seal ensures a 100% water-tight seal, eliminating water in the bilge and reducing wear on the propeller shaft.
  • Low Maintenance: By eliminating the need for constant adjustments and traditional packing glands, the PSS Shaft Seal significantly reduces maintenance and costs.

Product Specifications and Technical Details

The PSS 2in Shaft / 4in Tube Shaft Seal is specifically designed for shaft sizes ranging from 2.000" to 2.125" and stern tube diameters of 4.000" to 4.125". This versatile seal features a mechanical face seal design, where a rotating stainless steel rotor interacts with a stationary carbon flange. The carbon flange is attached to the stern tube with hose clamps, while the stainless steel rotor is fit on the shaft and secured with set-screws. This innovative design allows for easy retrofitting and provides excellent alignment and vibration compensation.
  • Material: Constructed from high-quality stainless steel and carbon materials for superior durability and corrosion resistance.
