1-1/4 in. Pipe Size - Standard Weight Rigid Coupling with "C" Gasket - Gasket Grade: E - EPDM - Finish: Galvanized - 66SR Cooplok Grooved Pipe Connections - UL/FM

FIG 65SR & 66SR Standard Weight Rigid Coupling with "C" Gasket

Figure 65SR & 66SR Standard Weight 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.
