Our multi-passage hydraulic swivel joint (rotary union) is a high-precision fluid transfer component designed for heavy-duty rotating equipment requiring multiple independent circuits. It enables seamless 360° continuous rotation while maintaining isolated, leak-free flow for 3 passages (hydraulic oil, air, water, etc.). Constructed from premium stainless steel/carbon steel with advanced multi-layer sealing technology, this swivel joint performs reliably under high pressure and high-speed rotation, eliminating cross-contamination and hose damage. Ideal for excavators, cranes, rotary drilling rigs, hydraulic power units (HPU), and industrial automation systems, it supports custom passage numbers, port sizes, and thread types to match complex multi-circuit system requirements.
✅ Multi-Channel Synchronous Transfer: Supports 2~8 independent passages (hydraulic oil, air, water, etc.) for simultaneous fluid delivery, meeting complex multi-circuit system needs without cross-contamination.
✅ 360° Free High-Speed Rotation: Enables continuous 360° rotation under high-speed conditions, eliminating torque transmission and hose twisting/kinking damage.
✅ Leak-Free & Isolated Sealing: Adopts multi-layer high-precision sealing (NBR/FKM/PTFE) with isolated passage design, ensuring zero leakage and no medium mixing under high pressure.
✅ Heavy-Duty Durability: Precision-machined from stainless steel/carbon steel, wear-resistant, corrosion-resistant, and impact-resistant, suitable for harsh working conditions (construction sites, mines, marine environments).
✅ Wide Compatibility & Customization: Fits excavators, cranes, rotary drilling rigs, HPUs, aerial work platforms, and industrial automation systems; customizable passage count, port size, thread type (BSP/NPT/metric), and pressure rating to replace original equipment.
