18 in. Pipe Size - Standard Weight Flexible Coupling with "C" Gasket - Gasket Grade: E - EPDM - Finish: Orange Enamel Paint - 65SF Cooplok Grooved Pipe Connections

FIG 65SF & 66SF COOPLOK Standard Weight Flexible Coupling with "C" Gasket

Figure 65SF & 66SF Standard Weight Flexible couplings are designed for use in piping systems where flexibility is desired.
They allow for pipe movement caused by seismic action and thermal variations, and will also attenuate noise & vibration transmitted through the piping system.
