COIL/TUBESHEET ORING PKG 400

The Coil/Tubesheet O-Ring Package for Pentair 400 Series Heater (77707-0119) is a set of replacement o-rings for the heat exchanger coil and tubesheet assembly in Pentair 400 series pool heaters (MasterTemp 400 and Sta-Rite Max-E-Therm 400). These o-rings seal the heat exchanger components within the heater body -- degraded o-rings can cause water leaks inside the heater cabinet. Replace during heat exchanger service or when leaks are detected in the heat exchanger area.
