Rudder horn seals are critical components in marine propulsion systems, ensuring watertight integrity around the rudder horn. 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, depending on vessel size.

Grade: Marine-grade seals compliant with ISO 9001 and ASTM standards.

Viscosity: Compatible with lubricants having a viscosity range of 150-460 cSt.

Buoyancy: Neutral to slightly positive buoyancy to prevent sinking.

Material: Nitrile rubber (NBR), Polyurethane (PU), or Fluorocarbon (FKM) for high chemical resistance.

Operating Temperature: -20°C to +120°C, depending on material.

Pressure Rating: Withstands up to 10 bar (145 psi) dynamic pressure.

Hardness: 70-90 Shore A for optimal sealing performance.

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

Installation: Designed for stern tube and rudder horn applications.

Service Life: 5-10 years, depending on operational conditions.

Rudder Horn Seals for Marine Propulsion typically comply with maritime standards such as ISO 8849, ISO 12215, or specific classification society requirements like ABS, DNV, or Lloyd's Register. For exact compliance, refer to the manufacturer's specifications or certification documents.
