Propeller Shaft Seal Kits for marine propulsion prevent water ingress and lubricant leakage around the shaft. These kits ensure smooth operation and protect propulsion systems from corrosion and damage. They are essential for maintaining vessel efficiency and longevity.

Size: Available in various diameters (e.g., 50mm to 500mm) to fit different shaft sizes.

Grade: Typically meets industry standards such as ISO, ASTM, or OEM specifications.

Viscosity: Compatible with lubricants having viscosities ranging from ISO VG 68 to ISO VG 220.

Buoyancy: Designed to withstand underwater pressures and maintain seal integrity.

Material: Constructed from nitrile rubber (NBR), polyurethane, or fluorocarbon (FKM) for durability and corrosion resistance.

Operating Temperature: -20°C to +120°C (-4°F to +248°F), depending on material.

Pressure Rating: Typically rated for 3-10 bar (43-145 psi) dynamic pressure.

Chemical Resistance: Resistant to seawater, oils, and greases.

Installation: Includes lip seals, O-rings, and gaskets for a complete sealing solution.

Applications: Suitable for marine propulsion systems, including stern tubes and rudder stocks.

Propeller Shaft Seal Kits, Marine Propulsion typically comply with maritime standards such as ISO 9001, ABS, DNV, or other relevant classification society standards depending on the manufacturer and application.
