PSS Shaft Seal Maintenance Kit 1 1/4" Shaft 2" Tube

The PSS Shaft Seal Maintenance Kit for 1 1/4" Shaft and 2" Tube (part number 07-114-200R) is a comprehensive service package designed for marine propulsion systems where shaft seals operate continuously below the waterline. This kit addresses the critical maintenance intervals required to prevent saltwater intrusion, corrosion, and seal failure in through-hull applications.

The kit contains replacement bellows, O-rings, and stainless steel set screws engineered to work together as a system. PSS bellows are subject to continuous flexing and exposure to salt water, UV radiation, and ozone, which cause rubber deterioration over time. PSS recommends bellows replacement on six-year intervals—more frequently in high-use, warm-water, or chemically aggressive environments. During bellows replacement, renewing the O-rings and set screws in the stainless steel rotor extends the service life of the entire seal assembly and reduces the likelihood of piecemeal failures that can compromise the primary seal.

This maintenance kit is essential for vessel operators, marine mechanics, and shipyard technicians responsible for through-hull seal integrity. Whether managing a commercial fishing vessel, offshore utility boat, or high-performance cruiser, timely replacement of bellows and internal rotor components prevents water ingress, gelcoat staining around the shaft tube, and catastrophic seal failure under load. Keeping a PSS maintenance kit on hand ensures rapid response to age-based or performance-based replacement schedules without extended downtime.

PSS shaft seals are recognized in the marine industry for precision engineering and long-term reliability in demanding saltwater environments. Selecting the correct shaft and tube diameter is essential—this kit is sized specifically for 1 1/4" shafts with a 2" tube OD. Verify your seal's dimensions before ordering to ensure compatibility with your propulsion system.
