Walvoil 1/4" BSP Inline Rotating Coupling Rotary couplings are designed to connect two hydraulic lines that move simultaneously at different speeds or in different directions. Suitable for both alternating and continuous rotations, these couplings ensure smooth operation and seamless fluid transfer in dynamic hydraulic systems. Easily installed by connecting the hydraulic lines to the rotary coupling ports, these units rotate on roller bearings via a mechanical coupling, providing exceptional stability and efficiency. Their special low-friction seals guarantee a perfect seal, even under maximum pressure, while maintaining low torque rotation. Made from zinc-plated and hardened steel components, these couplings offer long-lasting performance, zero leakage, and high resistance to wear. Optional features include a chromium-plated body, metric threads, and Viton seals, providing enhanced durability and compatibility for specialized applications. Ideal for high-performance hydraulic systems, rotary couplings ensure reliable fluid transfer and minimal wear, even under demanding conditions. 1/4" BSP 400 Bar 25LPM Inline
