Hydraulic hose fittings for marine hydraulics are specialized connectors designed to withstand harsh saltwater environments. They ensure leak-proof connections in high-pressure hydraulic systems on ships and offshore equipment. These fittings are typically made from corrosion-resistant materials like stainless steel or brass for durability.

Size: 1/4" to 2" (common sizes)

Grade: SAE 100R1, 100R2, 100R12, 100R13, 100R14, 100R15

Viscosity: ISO 32, 46, 68 (common hydraulic fluid grades)

Buoyancy: Typically neutral or slightly negative (depends on material and design)

Material: Carbon steel, stainless steel, brass, or corrosion-resistant alloys

Pressure Rating: 3,000 to 6,000 PSI (varies by type and size)

Temperature Range: -40°F to +250°F (-40°C to +121°C)

Thread Type: NPT, BSPP, JIC, ORFS, Metric

Compliance: SAE, ISO, DIN, and marine industry standards

Corrosion Resistance: High (marine-grade coatings or stainless steel)

End Connection Types: Flared, threaded, crimped, or reusable

Hydraulic Hose Fittings and Marine Hydraulics typically comply with maritime standards such as ISO 18752, SAE J517, and DNV standards, depending on the manufacturer and specific product specifications. Always verify with the supplier for exact compliance details.
