The Nozzle Diameter 8.5 is a fuel delivery component for burners, featuring an 8.5mm orifice size. This nozzle is designed to meter the flow of gas or oil, affecting combustion characteristics and efficiency. It is commonly used in larger burner systems where higher flow rates are required. Replacing a worn or incorrect nozzle with this size helps restore proper fuel-air mixture and flame shape. As a spare part for heating equipment, it supports reliable burner operation and is a typical item in boiler and burner maintenance kits.
