No more dripping stuffing boxes: The PSS Shaft Seal Type A is a low-maintenance mechanical face seal that seals your propeller shaft absolutely watertight. It reliably compensates for misalignments, vibrations, and the axial back-and-forth movement caused by propeller thrust – with no dripping water in the bilge.

Tip: The correct preload of the bellows is crucial for proper function. After installation, check the compression of the bellows and ensure that the rotor's set screws are seated on clean, degreased shaft metal. After the first few hours of operation, recheck all hose clamps for a tight fit.
