360° Hydraulic Swivel Joint

Our 360° hydraulic swivel joint (rotary union) is a precision-engineered component designed to transfer hydraulic fluid between stationary and rotating parts of heavy machinery. Featuring a robust stainless steel/steel construction and high-performance sealing elements, it allows continuous 360° rotation while maintaining leak-free performance under high pressure. Ideal for excavators, cranes, hydraulic power units, and rotating equipment, this swivel joint eliminates hose twisting, kinking, and torsion damage, significantly extending the service life of hydraulic hoses and improving operational safety. Customized sizes and thread types (BSP, NPT, metric) are available to meet diverse application requirements.

Key Features

✅ 360° Free Rotation: Enables continuous 360° rotation without torque transmission, completely avoiding hydraulic hose twisting, kinking and damage.
✅ High Pressure Resistance: Suitable for high-pressure hydraulic working conditions, with a rated pressure of up to 35MPa (5000PSI), meeting industrial-grade usage standards.
✅ Leak-Free Sealing: Adopts high-precision sealing structure and high-quality seal ring material, achieving zero leakage during rotation and ensuring system stability.
✅ Durable Material: The main body is precision-machined from stainless steel/carbon steel, wear-resistant and corrosion-resistant, suitable for harsh working conditions (such as construction sites, mines).
✅ Wide Compatibility: Suitable for various rotating hydraulic equipment such as excavators, cranes, hydraulic power units, and aerial work platforms, and can replace original accessories.
