Function: For your home pool and spa maintenance and upgrades, replace broken manifold components to restore heater efficiency and enjoy your pool or spa. Superior Replacement: Fits most sizes Pentair MasterTemp 175, 200, 250, 300, 400 and the Sta-Rite Max-e-Therm SR200, SR333, SR400. Our manifold does NOT fit the 125. The 125 or 125000 is Pentair’s smallest pool or spa heater. The 125 needs to use a smaller manifold.
