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

Tip: Correct bellows pre-tension is crucial for proper function. After installation, check the bellows compression and ensure that the set screws of the rotor rest on clean, degreased shaft metal. After the first few hours of operation, re-check all hose clamps for a tight fit.
