Product details

Flexible couplings allow for controlled linear and angular movement, which accommodates pipeline deflection as well as thermal expansion and contraction. Dimensions of the pipe coupling key are narrower than the groove in the pipe, providing room for the coupling key to move within the pipe groove.
