Hydraulic rotary unions enable the transfer of pressurized fluid between stationary and rotating components in hydraulic systems. They ensure leak-free rotation while maintaining fluid flow and pressure integrity. These unions are critical for applications requiring continuous rotation, such as heavy machinery and industrial equipment.

Hydraulic Rotary Unions:
Size: 1/4" to 2"
Pressure Rating: Up to 5000 psi
Temperature Range: -40°F to 250°F
Material: Stainless steel, carbon steel, brass
Viscosity Compatibility: ISO 10 to ISO 460
Rotation Speed: Up to 1000 RPM
Seals: Nitrile, Viton, PTFE

Hydraulic Systems:
Size: Varies by application (small to large-scale)
Pressure Rating: 1000 psi to 10,000 psi
Temperature Range: -20°F to 300°F
Fluid Grade: ISO 32, ISO 46, ISO 68 (common)
Viscosity: 10 to 1000 cSt (depending on fluid)
Material: Steel, aluminum, composite hoses
Buoyancy: Dependent on fluid density and system design

Hydraulic rotary unions and hydraulic systems may comply with maritime standards such as ISO 4401, ISO 6162, or other relevant industry-specific certifications depending on the manufacturer and application. It is recommended to check with the supplier for specific compliance details.
