Exact OEM Replacement: Directly substitutes thermopiles 6911197, 9007872005, 100094024, 100112328 with identical 21" length and 3/8" flare fittings 750mV Stable Output: Generates consistent 720-775mV under load (UL 353 testing standard), preventing gas valve lockout due to voltage drop Wide Temp Range: Operates from -20°F to 180°F (-29°C to 82°C) for attic/garage installations Leak Prevention: Pre-applied anti-seize compound on threads ensures airtight seal Tool-Free Installation: Flexible tubing allows direct swap without brazing; complete in 15 minutes As a direct replacement for water heater thermopiles (OEM # 69111197900782005100094024100112328), this 750mV mini volt thermocouple can provide stable voltage output even after more than 15000 ignition cycles. Accurate calibration maintains an output tolerance of ± 25mV within the working range of -20 ° F to 180 ° F, ensuring reliable operation of gas valves in extreme attic/garage environments. The 21 inch flexible copper alloy tube allows for tool free installation without brazing: simply disconnect the old device → thread the new thermopile into the test component → tighten the installation nut. Including thread sealant for leak proof connections.
