Product Description

Pentair MasterTemp 175 200 Tube Sheet Coil Assembly Kit 474058

Restore heat to your Pentair MasterTemp 175NA with the genuine OEM 474058 tube sheet coil assembly kit. When the heat exchanger coil leaks or scales up, this kit replaces the finned coil and tube sheet together with fresh O-rings, insulation, gaskets, and sealant, so a failed exchanger does not mean replacing the whole heater.

🚩 PRO TIP: Heat-exchanger work is for a qualified technician only — isolate the gas and water, drain the heater, replace every O-ring and gasket in the kit, and pressure- and leak-test the reassembled heater before returning it to service. Match the part number on your existing coil kit before ordering.
