PSS 02-28M-112 - Dripless Shaft Seal 28 mm, 1 1/2" Stern Tube

The PSS 02-28M-112 Dripless Shaft Seal is designed for reliable performance in marine environments, offering a robust solution for sealing your stern tube. This mechanical face seal ensures a watertight seal by leveraging the interaction between stainless-steel and carbon components, providing durability and flexibility to accommodate various operational conditions.
- Type: Mechanical face seal
- Sealing Surface: Rotating stainless-steel rotor and stationary carbon flange
- Attachment: Carbon flange secured to the bellows with hose clamps; bellows fits over stern tube and is secured with hose clamps
- Compression: Stainless-steel rotor compresses the bellows, ensuring constant contact between the rotor and flange
- Misalignment Compensation: Carbon flange “floats” around the shaft to address misalignment and vibration
- Sealing: Two O-rings recessed into the collar’s bore rotate with the shaft and rotor, preventing wear
