PSS 1″Shaft 1.5″Tube Shaft Seal – 02-100-112

Description

PSS 1’³ Shaft 1.5’³ Tube Shaft Seal – 02-100-112

PSS 1’³ Shaft 1.5’³ Tube Shaft Seal – 02-100-112. This dripless mechanical shaft seal replaces conventional stuffing boxes with a reliable face seal system designed to keep bilges dry and maintenance to a minimum. The system uses a precision-machined stainless steel rotor that presses against a stationary carbon flange, creating a watertight seal while allowing smooth shaft rotation.

• Designed for 1″ propeller shafts.
• Fits 1-1/2″ stern tube diameter.
• Dripless mechanical face seal eliminates traditional packing gland leakage.
• Carbon stator and stainless rotor create a durable sealing surface.
• Simple installation with replaceable bellows and set screw locking system.

The PSS shaft seal is widely used on both sailboats and powerboats as a dependable upgrade from traditional packing glands. By eliminating the need for constant adjustment and reducing bilge water, it helps keep engine rooms cleaner and improves overall drivetrain reliability.

The seal is compressed during installation to maintain constant pressure between the sealing faces. As the shaft rotates, the polished stainless rotor and carbon flange maintain a smooth sealing interface while seawater lubricates the surfaces during operation.
