Product Overview
The Pentair 474974 Union Kit is a service replacement part used in the water connection assembly of compatible MasterTemp 125 and Max-E-Therm heaters. Its primary role is to provide a secure and removable 1.5 inch plumbing connection so water can move through the heater correctly during normal operation. Because heater plumbing connections are exposed to water pressure, temperature changes, and routine service work, the union assembly plays an important role in maintaining dependable flow and sealing performance.
This kit is well suited for repair situations where the heater remains otherwise serviceable but the original union connection has become worn, damaged, or no longer seals correctly. The union-style format also makes future maintenance easier by allowing the heater to be disconnected more cleanly when service is needed. For pool and spa service professionals maintaining compatible MasterTemp 125 and Max-E-Therm heaters, the 474974 fills an important role in restoring proper water connection integrity and dependable heater operation.
