Product Details

The P.S.S. (Packless Sealing System) Shaft Seal by PYI Inc. is a modern mechanical face seal assembly that replaces a traditional rope style packing gland. The P.S.S. is the number one selling brand on the world market and is installed by production boat builders and the U.S. Coast Guard as standard equipment.

The dripless operation of the P.S.S. eliminates needless bilge pumping and minimizes corrosion. It reduces maintenance, ending the need to adjust packing or having to repair shaft damage due to the packing gland.

Shaft and stern tube (shaft log) diameters are both needed when ordering.
