8-Port with Four-Bolt Flanges
Rotary Union | Hydraulic Swivel
The 8-port rotary union features four-bolt flanges as part of its design. It is a swivel joint designed for smooth, reliable transfer of fluid between stationary and rotating components.
Unlike smaller port models, the 8-port design is engineered for advanced equipment where multiple hydraulic circuits must work together without interruption. Its four-bolt flange mount secures the union firmly in place, even under heavy loads and continuous rotation. The precision-machined body and premium sealing system provide consistent, leak-free operation across all passages.
This rotary union is purpose-built for large-scale agricultural implements, industrial automation systems, construction rigs, and specialized mobile equipment.
Highlights:
- Eight fully independent flow passages for complex, multi-function hydraulics
- Four-bolt flange mounts for strong, stable installation
- Precision-machined body for accurate fit and long service life
- Sealing system for dependable, leak-free operation
Our rotary unions can be adapted or custom-built to match your specific requirements.
