Meter Star 39.5 Inch Gas Heater Thermocouple with M8x1 Nuts for Vent-Free Wall Heaters

If a vent-free wall heater will not light properly or will not stay on, a worn thermocouple may be the issue. This Meter Star 39.5-inch replacement thermocouple monitors the pilot flame and supports the gas safety shutoff function when the flame goes out.

The copper assembly features a polished finish for heat transfer and corrosion resistance. The sensing head is rated for high-temperature resistance up to 650°C (1202°F), and the fast-acting design supports a valve opening time of less than 10 seconds during ignition.

Standard M8x1 connection nuts help provide a secure fit on compatible heater systems. This replacement part is intended for select vent-free natural gas or propane wall heaters that match the required thermocouple length and connection size.

Package includes one complete 39.5-inch thermocouple assembly for direct replacement. This is an aftermarket replacement part and is not an original manufacturer component. Always confirm heater model compatibility and M8x1 connection size before purchase.
