Product Description

Pentair MasterTemp 400 Tube Sheet Coil Assembly Kit 474061

Restore heat to your Pentair MasterTemp 400NA and 400LP heaters and Sta-Rite Max-E-Therm SR400NA and SR400LP heaters (New Tub Design; Max-E-Therm after 1/12/09) with the genuine OEM 474061 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.
