8-Port Rotary Union | Hydraulic Swivel | Standardized Design
For hydraulic systems with high circuit density, an 8-port rotary union provides the capacity to route multiple fluid paths through a single rotating interface. This configuration is used in advanced equipment where several hydraulic functions must operate simultaneously, and consolidating those connections helps reduce system complexity and external plumbing.
Designed around a standardized swivel housing, this unit allows for flexible integration into a wide range of machinery. Multiple mounting hole patterns are built into the body, making it easier to adapt mounting plates or torque arms to match specific equipment layouts without extensive customization.
The 8-port rotary union supports eight independent hydraulic passages within one assembly, making it a strong fit for complex systems that require multiple pressure, return, and auxiliary lines. Each unit is equipped with SAE ORB ports and is intended for hydraulic fluid applications where consistent performance is required across multiple circuits.
Where an 8-Port Design Fits
- Equipment with high circuit requirements where multiple hydraulic functions must pass through a rotating joint
- Commonly used in large cranes, drilling systems, and heavy equipment with numerous auxiliary functions
- Ideal for rotating platforms and specialized machinery with advanced, multi-function hydraulic systems
Models shown below are engineered specifically for hydraulic fluid compatibility.
Key Features & Benefits
- Eight independent flow paths to support high-capacity, multi-circuit hydraulic systems
- Standardized swivel housing to simplify integration and reduce engineering time
- Multiple mounting hole patterns for flexible installation across equipment designs
