A flare wrench, also known as a flare‑nut or line wrench, is a specialized hand tool designed for tightening and loosening fasteners on soft metal fittings and round tubing assemblies. Its partially enclosed head features a narrow slot that allows the wrench to slide over tubing while maintaining contact with five or more sides of the fastener, providing significantly greater grip than a standard open‑end wrench.
