Rubber flexible connectors serve three prim ary functionsin piping systems,to accept all directional movements,minimizing pipe 'stressesand compensate thermalexpansionand contraction. Rubber fiexible connectorintegrates the functions of expansion joint, flexibleconnector and vibration isolator into one.As expansionjoints, they  compensate for pipe thermal movement,eliminating the need for expansion loops which requiread ditional material and space.As flexible connectors, theflexibility of the EPDM carcass makes them ideal flexibleconn ectors for handling minor misalignment and offsetproblems. Asflexible connectors, they protect pipingsystem against hamful "start-up" and surge forces.
Rubber flexible connectors are used on both hot andchilledwater circulation lines,suction and dischargesides of chiller. pumps, cooling towers,etc.
Rubber flexible connector series have four types:singlesphere floating flanges,single sphere restrained flanges.twin sphere floating flanges, and twin sphere restrainedflanges.  Twin sphere type offers more offset tomisalignment and thermai movement,more eliminationtovibrationand noise transmission. Restrained typeoffers extra protection to connectors.
