Flat Nut G1" De Dietrich 721688300

A flat nut with a G1" thread is a common component used in heating systems to secure connections on pipes and fittings. This type of nut is designed to provide a tight seal when paired with a corresponding threaded male end, ensuring leak-free operation in boiler and burner assemblies. Its flat profile allows for easy installation with standard wrenches, making it a practical choice for maintenance and repair tasks on gas burners and other heating equipment components.
