Cary offers 3 standard models of rotating unions with a wide range of port sizes and thread configurations. Available are single flow, double flow, and a special compact double flow. Also available are double flow elbows, stationary feed tubes and connecting hose assemblies.
The dependable, leakproof Cary rotating union works on the face sealing principle and features precision mating carbon seals and ceramic seats. The surfaces have a surface of four (4)rms and are lapped to obtain a true flatness of two (2) light bands or .000023 inch and inspected by optical testing. After assembly each union is bench tested to assure no leakage and is free of other abnormalities before a Cary label is applied.
"O" Series Union
NOTE: Rotors with left hand threads are notched.
The Cary Compact Double Flow Union is specially designed to fit into limited areas. The double flow configuration is achieved within the standard O-series outline dimensions. No external double flow elbow is required. Except for the special endcap, all components are interchangeable with the standard O-series Union.
"O-1/2" Series Union
NON-STOCK ITEM - SPECIAL ORDER ONLY
The O1/2 Series unions, like the smaller O and R series have an unobstructed flow path which reduces the pressure loss and minimizes the tendency for mineral deposits to form. Very high Cv's are achieved within a modest overall size. This series is available in stainless steel only with high temp Viton seals. It is used primarily for the bottling industry and complete rebuild kits are available.

Double Flow Elbow
Cary double flow unions are used when the fluid introduced into rotating cylinder, drum, or shaft must be withdrawn from the same side. The Cv for double flow unions is primarily determined by the feed tube. See approximate values listed.
