Figure 65LR & 66LR Lightweight Rigid couplings are designed for use in piping systems when rigid piping connections are desired. The angle-pad design allows the coupling housing to slide when tightened. This provides offset clamping that creates a rigid joint resistant to flexural and torsional loads.
