A complete replacement or upgrade control assembly for gas grills, heaters, fire pits and fireplaces that combines a user control valve, a knob switch and a 600 mm thermocouple with an M8*1 threaded head. Designed to restore safe operation and reliable flame sensing where a combined valve/thermocouple solution is required. Key benefits Restores safe operation: the included thermocouple provides flame sensing to help shut off gas if the pilot or burner goes out. Simple control: the integrated knob switch gives straightforward on/off and adjustment control for the connected appliance. Long reach for flexible routing: the 600 mm thermocouple length allows easier installation and positioning of the sensor relative to the pilot flame. Direct fit where specified: the thermocouple's M8*1 threaded head makes it compatible with appliances that accept an M8*1 connection. Main attributes Functionality: control valve with integrated knob switch plus thermocouple for flame detection and gas control. Thermocouple length: 600 mm (provides routing flexibility). Thread specification: thermocouple threaded head M8*1 (for matching ports). Intended applications: gas grill, heater, fire pit, fireplace. Typical use cases a worn or failed control valve/thermocouple on a backyard gas grill to restore reliable pilot sensing and knob control. Upgrade or the safety control assembly on an outdoor fireplace or fire pit that requires a 600 mm thermocouple with an M8*1 thread. Install in a small gas heater or custom appliance project where a single assembly combining valve control and a 600 mm thermocouple is needed. Compatibility and installation notes Designed for use with gas grills, heaters, fire pits and fireplaces that accept an M8*1 thermocouple connection and require a combined control valve with knob switch. Verify that your appliance uses an M8*1 thermocouple thread and that 600 mm thermocouple length meets your routing needs before installation. Basic installation practices: shut off gas supply before replacing components, confirm thread alignment before tightening, and test for proper flame sensing and control after installation. What's included Control valve with knob switch and attached thermocouple (600 mm) terminating in an M8*1 threaded head. This assembly provides a direct and practical solution for restoring or installing a combined gas control and flamesensing component in compatible grills, heaters, fire pits and fireplaces.
