Rheem SP20064 – Thermocouple and Burner Gasket Kit for FVIR Gas Water Heaters

The Rheem SP20064 is a factory-authorized thermocouple replacement kit engineered for use with select FVIR (Flammable Vapor Ignition Resistant) gas water heaters. It is designed to replace the thermocouple and reestablish a secure seal at the burner access panel after service, ensuring safe ignition control and combustion chamber integrity.

This kit includes both the burner door gasket and associated fasteners along with a replacement thermocouple and support components. It is compatible with several Rheem, Ruud, Richmond, and GE brand water heaters using FVIR technology.
