FIGURE 640 PIVOT-BOLT RIGID COUPLING
THE FIGURE 640 PIVOT-BOLT RIGID COUPLING joins rolled grooved, hard-drawn copper tubing systems ten times faster than traditional joining methods and in less than half the time of other standard grooved couplings. It provides a rigid joint by firmly gripping the entire circumference of the copper tube groove. Only one bolt on the coupling requires tightening.
