Whether you need a single-channel rotary union or multi-passage hydraulic swivel, we deliver the performance and durability your system needs. Built for demanding industrial environments, this rotary union delivers superior reliability, leak-free operation, and long service life, making it an essential component for hydraulic systems in manufacturing, automation, and heavy equipment.

Key Features of Hydraulic Rotary Union

Robust Construction for High-Pressure Systems

Crafted from hardened stainless steel or carbon steel housing, the rotary union withstands up to 5000 PSI of hydraulic pressure. The corrosion-resistant body ensures long service life even in hostile outdoor or marine environments.

Leak-Free Sealing Technology

Utilizing high-performance elastomeric seals or mechanical face seals, our union ensures leak-tight fluid transfer across rotating interfaces. This reduces fluid loss, contamination, and potential safety hazards.

Low Friction, High-Speed Operation

Advanced ball or roller bearing configurations allow smooth operation at speeds up to 3000 RPM, minimizing heat buildup and mechanical wear—ideal for dynamic hydraulic actuation systems.

Single & Multi-Passage Options

Choose between single-flow rotary unions for simple hydraulic lines or multi-channel hydraulic rotary joints for complex systems transferring multiple fluids or integrating pneumatic and electrical slip rings.

High-Pressure Hydraulic Compatibility

Designed to handle hydraulic oils and fluids safely under high pressure, ensuring stable fluid transfer without leakage.

Dual or Multiple Passage Options

Available with single or multiple flow channels to accommodate complex hydraulic circuits requiring simultaneous fluid transfer.

Balanced Mechanical Seals

Utilizes premium carbon graphite and tool steel seals that reduce friction and wear, extending seal life and enhancing reliability.
