Hydraulic piston seals are critical components designed to prevent fluid leakage in hydraulic systems, ensuring efficient operation under high pressure. Marine hydraulics utilize these seals in harsh environments, offering resistance to saltwater, corrosion, and extreme conditions. They enhance performance and longevity in marine applications like steering systems, winches, and cranes.

Size: Typically ranges from 5 mm to 500 mm in diameter, depending on application.

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

Viscosity: Compatible with hydraulic fluids with viscosity ranges of 15 cSt to 460 cSt at 40°C.

Buoyancy: Generally neutral buoyancy in marine environments, depending on material density.

Material: Nitrile rubber (NBR), Polyurethane (PU), or Fluorocarbon (FKM) for corrosion and seawater resistance.

Temperature Range: -30°C to +100°C for standard materials, up to +200°C for specialized compounds.

Pressure Rating: Up to 400 bar dynamic, 600 bar static for high-performance seals.

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

Hardness: 70-90 Shore A for optimal sealing and durability.

Standards: Meets ISO 3601, DIN 3771, and other marine hydraulic specifications.

Hydraulic piston seals and marine hydraulics may comply with maritime standards such as ISO 9001, ISO 14001, or specific classification society standards like DNV, ABS, or Lloyd's Register, depending on the manufacturer and product specifications. Always verify with the supplier for exact compliance details.
