PSS Shaft Seal Maintenance Kit 2" Shaft 2 3/4" Tube

The PSS Shaft Seal Maintenance Kit for 2" Shaft and 2 3/4" Tube is a complete preventive maintenance solution designed for marine and industrial propulsion systems where shaft seals operate below the waterline. This kit addresses the critical need to maintain PSS bellows integrity, which deteriorates over time due to rubber aging, wear, and chemical exposure in saltwater and freshwater environments.

PSS bellows are engineered to prevent water ingress at the shaft penetration point, but rubber compounds degrade under continuous immersion. Industry best practice calls for bellows inspection at regular intervals and replacement every six years, even if no visible damage is apparent. This kit includes replacement bellows matched to 2" shaft and 2 3/4" tube dimensions, along with the o-rings and set screws for the stainless steel rotor. Replacing all these components during maintenance prevents leakage and extends the operational life of the entire seal assembly, avoiding costly water intrusion damage.

This maintenance kit is essential for vessel operators, marine engineering technicians, and industrial facilities running shaft-driven systems in saltwater conditions. Bellows may require more frequent inspection in environments with high water temperatures, aggressive chemical exposure, or extended dry-docking cycles. Performing planned bellows replacement during routine haul-outs prevents emergency repairs and keeps backup systems operational. The PSS system is recognized across the marine industry as a reliable shaft sealing solution when properly maintained.

Part number 07-200-234R is engineered to OEM specifications for PSS sealing applications. Proper maintenance intervals depend on operational hours, water conditions, and loading—check your vessel's maintenance log and consult PSS documentation for your specific installation to determine replacement frequency and ensure continued seal performance.
