PYI PSS Seal Shaft

The PSS (Packless Sealing System) Shaft Seal by PYI is the world's number-one selling mechanical face seal, designed to eliminate the mess and maintenance of traditional packing glands. This technically advanced system uses a carbon-graphite flange and a stainless steel rotor to create a 100% watertight seal that does not wear the propeller shaft. Freeport Marine Supply carries PSS seals to provide you with a dry bilge and the peace of mind that comes with a maintenance-free shaft seal.
