Stern Tube Seal Kits are essential components in marine propulsion systems, ensuring watertight integrity around propeller shafts. These kits prevent seawater ingress and lubricant leakage, maintaining efficient vessel operation. They are designed for durability and easy maintenance in harsh marine environments.

Size: Available in various diameters ranging from 50 mm to 800 mm to accommodate different stern tube dimensions.

Grade: Typically classified as marine-grade, compliant with ISO 9001 and other maritime standards.

Viscosity: Lubricating oil viscosity ranges from ISO VG 68 to ISO VG 220, depending on application requirements.

Buoyancy: Designed to withstand hydrostatic pressures up to 10 bar, ensuring effective sealing in submerged conditions.

Material: Constructed from high-quality nitrile rubber (NBR), polyurethane, or other elastomers for durability and resistance to seawater and oils.

Temperature Range: Operates effectively between -20°C to +80°C, suitable for most marine environments.

Pressure Rating: Capable of handling pressures up to 0.5 MPa (5 bar) for standard applications.

Seal Type: Lip seals, radial seals, or face seals, depending on stern tube design and propulsion system.

Compatibility: Compatible with mineral oils, synthetic lubricants, and seawater.

Installation: Pre-assembled kits for easy installation, including sealing rings, gaskets, and fasteners.

Stern Tube Seal Kits for Marine Propulsion typically comply with maritime standards such as ISO 9001, ISO 14001, and may adhere to classification society requirements like ABS, DNV, LR, or BV depending on the manufacturer and specific product specifications.
