9300 Rotary Unions

Talco, Inc. manufactures and customizes a variety of coaxial rotary unions (also know as coaxial rotary joints or coaxial swivel joints) for liquid or gas transfer applications in such industries as Process Equipment, Crane, hose reel, and car wash equipment.

Rotary unions, sometimes also called rotary valves or rotary manifolds, are used in a variety of manufacturing and other processes to permit the flow of heat transfer media, such as Air, water, thermal and hydraulic oil, or coolant, from a stationary supply pipe to a moving part, such as a rotating drum or cylinder.  The liquid or gas medium is contained within the rotary union or joint with the use of a mechanical seal and seal ring.

The 9300 Series rotary union can feature an NPT or BSP Thread, and a steel rotor and aluminum housing (or can be constructed in all stainless steel, if desired, for especially tough environments).

We at Talco are also happy to do custom work. Just give us the specifications for the special custom rotary joint or coolant union your application requires. We specialize in adapting our products to fit your machines, RPM’s, temperature ranges and pressure requirements. Contact our engineering department with your needs
