Built from steel with a satin finish, it features a 12-point head configuration and measures 7.5 inches overall length. The double-end design provides two sizes in one tool, with jaw openings of 1\/2 inch and 9\/16 inch. This wrench is a standard hand tool for licensed HVAC technicians and plumbers working on refrigerant line sets, fuel lines, and hydraulic or pneumatic fittings where a standard open-end wrench would risk rounding the nut.\u003c\/p\u003e\u003cp\u003eThis wrench is suited for residential and light commercial service work involving flare fittings on copper refrigerant lines, fuel oil lines, and similar tubing assemblies. The 1\/2-inch and 9\/16-inch jaw sizes cover common flare nut dimensions found throughout HVAC, refrigeration, and plumbing systems. It is a practical addition to any field service kit where fitting integrity and accessibility around tubing runs are concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end head provides 1\/2-inch and 9\/16-inch jaw openings in a single tool\u003c\/li\u003e\n\u003cli\u003e12-point open-end head design for improved grip on flare and tube nuts\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in field and shop environments\u003c\/li\u003e\n\u003cli\u003eSatin finish reduces glare and provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003e7.5 inches overall length for access in confined service areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard open-end flare nut wrench suitable for use with 1\/2-inch and 9\/16-inch flare fittings and tube nuts commonly found in HVAC, refrigeration, plumbing, and fuel line applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is used by HVAC technicians and plumbers during installation or service of flare-fitted tubing systems.
