System Safety: Prevents catastrophic heat exchanger failure by instantly cutting the gas valve circuit if the supply plenum exceeds 200°F

Universal Fit: Standardized round profile ensures compatibility with most dual and single-capacitor mounting brackets

this component features a precise 145°F opening temperature to interrupt the burner circuit upon detecting an overheat condition

simplifying inventory and parts matching for contractors

the 100208087 is technically identical to the GKT2012 and GKT2012K part numbers

Mueller W01063 1-5/8" Coupling System Safety: Prevents catastrophic heatThe Mueller W01063 is a professional grade 1 5 8" copper coupling engineered for high pressure HVACR and potable water applications. This wrot copper fitting (WC 400 series) features a rolled tube stop to ensure precise alignment and mechanical integrity during the brazing or soldering process. Built from UNS C12200 alloy, the coupling provides superior thermal conductivity and corrosion resistance, essential for maintaining system performance in
