Fixing or upgrading your propane fire pit? This Lemfema gas control valve kit is a solid replacement part. It's designed for low-pressure propane systems only (max 50,000 BTU, working pressure 65 mbar/1/2 PSI). The valve body is brass with zinc alloy knob, and it includes a 600mm (23.62\) long thermocouple with M8 thread. Inlet and outlet are both 3/8\ flare male threads (5/8-18UNF). The \D\ axis is 6.1mm. This is a flame failure safety valve - it automatically shuts off gas if the pilot light goes out. Handy for fire pits, patio heaters, grills, or fireplaces. Installation is pretty straightforward: mount valve vertically, connect gas lines and thermocouple, secure with screws. Includes valve, knob, and thermocouple. Check your existing setup for compatibility first! Comes with a 6-month warranty and helpful customer support if you need it.
