The Hot Oil Rotary Union / Joint is a high-performance mechanical device designed to transfer hot oil (thermic fluid), steam, or water from a stationary source into rotating machinery. It is specifically engineered for high-temperature applications where reliable sealing and smooth rotation are critical for heating processes and fluid power transmission.
These rotary unions are manufactured using heat-resistant materials and advanced sealing technology to ensure consistent performance under extreme temperatures. Equipped with graphite bush bearings and tungsten carbide seals, the Hot Oil Rotary Union delivers excellent durability, minimal leakage, and long service life. Each unit can be customized to match the exact operating conditions and application requirements of the customer.
