ULTRASPHERE TWIN EXPANSION JOINT

The Ultrasphere is the the most widely applied rubber expansion joint available today, and the Ultrasphere Twin provides a bit more movement.

The floating metal flanges on these expansion joints freely rotate for easy installation, and it comes with tapped holes which eliminate the cost of nuts.  Drilled holes are also available, as are metric and stainless flanges.

The Ultrasphere Twin with Cables is just like the Ultrasphere Twin with one big difference: no control units are required.  The cables that are supplied at the factory act as control units, which are normally installed in the field.  The optional control units may be critical for your application, and must be carefully considered. 

Also available are Ultrasphere Twin Unions expansion joints, which are used for connecting pipes and equipment where threaded union ends are preferred. Large inventories of Ultraspheres are kept at the Flexicraft warehouses for quick delivery.  Stocked in EPDM, neoprene, and nitrile.
