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.

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.
