A mechanical seal is created by the contact of a turning surface against a stationary surface. In the case of the PSS Shaft Seal, the stationary surface is a carbon flange held in contact against a stainless steel rotor which turns with the shaft. The carbon flange is attached to the boat by a nitrile bellow which, with the help of water pressure, produces a constant contact between the carbon and the stainless steel ring. These type of seals are unaffected by engine motion or vibrations. The result is a 100% watertight and totally maintenance-free seal.

Available to suit a range of propeller shaft sizes sizes from 3/4"-3 3/4"

Stern tube Outside diameter (OD) to be specified when ordering. If your outside diameter of your stern tube is oversize, there is an additional charge.
