Description
The sealing system is one of the most important parts of the rudder system. However, a leaky sealing system is irritating and dangerous. The PSS Shaft Seal is a great solution as it offers ultimate reliability for rudder seals due to the simple design. Available for 3/4″ to 6″ (20mm to 150mm) shaft diameters. And has service parts available from stock.

How Does It Work?
- Step 1: Two nitrile o-rings seal the stainless steel rotor to the shaft and will not experience wear.
- Step 2: A primary set screw and a backup set screw (2 sets) are used to secure the stainless steel rotor to the shaft.
- Step 3: A seal is created between the two flat surfaces of the carbon stator and the stainless steel rotor.
- Step 4: The stationary carbon stator is attached to the nitrile bellows, which is attached to the stern tube (shaft log).
