Control Units
control unit

Control units are recommended for use on Ultra-Sphere connectors when it is not possible to install solid anchors in the piping system. Although it is theoretically possible to pre-elongate spherical connectors to avoid the effects of extension due to pressure thrust forces, Unisource does not recommend this practice in lieu of anchors and control units due to the unpredictability of subsequent pressure spikes and system pressure tests. To isolate vibration that could travel across solid control rods, Unisource utilizes minimum 1/4” thick reinforced grommets on each end of our control unit rods.

A standard control unit set consists of two threaded rods, four triangular plates, eight steel nuts, four flat washers, and four 1/4” thick rubber grommets. Always consult the system engineer to determine the highest pressures that the system will see to determine the number of rods needed. Unisource control units are based on Fluid Sealing Association standards and are rated to equal or exceed the following specifications:
