Chesterton 442-36 Split Mechanical Seal for Pumps is a split mechanical seal identified by part number 442-36, configured for a 4.5 shaft size and a -36 seal size. It is intended for use in pump assemblies to seal rotating shafts and prevent leakage at the pump interface. The 4.5 shaft size specifies the diameter the seal is designed to fit, while the -36 seal size defines its sealing interface. By pairing a split construction with these precise dimensions, this unit is designed for installations where a 4.5 shaft and -36 sealing interface match the pump housing, providing a reliable sealing solution within compatible pump configurations.
