Honeywell Q340A Universal Thermocouple Kit – 30″ Length, Push-In Clip, For Pilot Burners in Gas Furnaces and Water Heaters

Honeywell Q340A Universal Thermocouple Kit – 30″ Length, Push-In Clip, For Pilot Burners in Gas Furnaces and Water Heaters

Condition: Used. May show signs of wear or minor residue from prior installation.
The Honeywell Q340A Universal Thermocouple Kit is a robust and reliable safety component designed for use in standing pilot gas-fired heating appliances, such as furnaces, water heaters, and boilers. The thermocouple generates a millivolt signal in response to heat from a pilot flame, providing safety shutdown capability by interrupting gas flow if the pilot goes out. The Q340A kit is engineered to replace a wide variety of thermocouple models and includes adapters to facilitate universal installation.

This thermocouple is 30 inches long, suitable for most standard residential applications. It features a durable copper sheath for long service life and consistent signal output. The kit includes necessary hardware for mounting and connection to most pilot assemblies, making it an ideal replacement solution in the field.
