Hydraulic piston rod seals in marine hydraulics prevent fluid leakage and maintain pressure within hydraulic systems. These seals are designed to withstand harsh marine environments, including saltwater and high pressures. They ensure smooth operation and longevity of hydraulic cylinders in marine applications.

Size: Typically ranges from 10 mm to 500 mm in diameter.

Grade: High-pressure hydraulic seals, often rated for 250 bar to 400 bar.

Viscosity: Compatible with hydraulic fluids of ISO VG 32 to VG 68.

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

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

Temperature Range: -30°C to +100°C (NBR), -20°C to +120°C (FKM).

Pressure Range: Up to 400 bar dynamic, 600 bar static.

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

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

Surface Finish: Requires rod surface roughness of Ra 0.1 to 0.4 µm for effective sealing.

Yes, Hydraulic Piston Rod Seals for Marine Hydraulics typically comply with maritime standards such as ISO 9001, ISO 14001, and may meet specific requirements from classification societies like DNV, ABS, or Lloyd's Register.
