4-Port Rotary Union | Hydraulic Swivel
United Equipment Accessories’ 4-Port Rotary Unions and Hydraulic Swivels are engineered for efficient and reliable fluid transfer in high-use hydraulic systems. Designed for smooth, continuous rotation, these rotary joints provide a secure, leak-resistant connections between stationary and rotating components.
Well-suited for off-highway equipment, industrial automation, and heavy machinery, UEA’s 4-Port Rotary Unions provide reliable fluid transfer with exceptional durability and precise performance in complex hydraulic systems.
Models shown below are engineered specifically for hydraulic fluid compatibility.
- Multi-Channel Fluid Transfer: Four independent ports facilitate the controlled flow.
- Precision Sealing Technology: Prevents leaks and produces long-lasting, reliable performance.
- Customizable Solutions: Configurable designs to meet specific application requirements.
- Industrial-Grade Build: Designed to withstand high-pressure spikes and operate reliably in extremely dirty environments.
Rotary Union designs can be modified or customized per your specifications.
