Rudder Stock Seals Supplier - Marine Propulsion

Rudder stock seals are critical components in marine propulsion systems, preventing water ingress and lubricant leakage. They ensure smooth operation and longevity of the rudder assembly by maintaining a watertight barrier. These seals are designed to withstand harsh marine environments, including high pressures and corrosive conditions.

Size: Typically ranges from 50 mm to 500 mm in diameter.

Grade: High-performance elastomers, often meeting ISO 6194 or DIN 3760 standards.

Viscosity: Compatible with lubricants having viscosities between 150-460 cSt.

Buoyancy: Neutral buoyancy materials to minimize drag and ensure stability.

Material: Nitrile rubber (NBR), polyurethane (PU), or fluorocarbon (FKM) for chemical resistance.

Pressure Rating: Up to 40 bar (580 psi) depending on design.

Temperature Range: -30°C to +120°C (-22°F to +248°F).

Hardness: 70-90 Shore A for durability and flexibility.

Seal Type: Lip seals, radial shaft seals, or mechanical face seals.

Compatibility: Resistant to seawater, oils, and marine fuels.

Rudder Stock Seals and Marine Propulsion products typically comply with maritime standards such as ISO, ASTM, or specific classification society requirements like DNV, ABS, or LR. For exact compliance, refer to the product specifications or manufacturer documentation.
