Rudder pintle seals are critical components in marine propulsion systems, ensuring watertight integrity at the rudder's pivot points. They prevent water ingress and lubricant leakage, enhancing operational efficiency and longevity. These seals are designed to withstand harsh marine environments and constant movement.

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

Grade: High-performance elastomeric compounds, often meeting MIL-SPEC or ASTM standards.

Viscosity: Not directly applicable; seals are solid elastomers.

Buoyancy: Neutral to slightly negative, depending on material density.

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

Temperature Range: -30°C to +120°C, depending on material.

Pressure Rating: Up to 50 bar (725 psi) for high-grade seals.

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

Chemical Resistance: Resistant to seawater, oils, and hydraulic fluids.

Installation: Designed for stern tube or rudder pintle applications in marine propulsion systems.

Rudder Pintle Seals for Marine Propulsion typically comply with maritime standards such as ISO 9001, ASTM F1518, and other relevant classification society requirements like ABS, DNV, or LR.
