Gearwrench 81907 Flare Nut Wrench Set 6 Pc Sae

Product Description

The GEARWRENCH 81907 is a 6-piece SAE flare nut wrench set designed for technicians who work with fuel, brake, and refrigerant line fittings. Each wrench features a 15-degree head offset angle that provides knuckle clearance in tight engine bays and equipment cabinets. The 6-point jaw profile grips hex fittings on three flats simultaneously, reducing the risk of rounding soft brass or steel flare nuts. The polished chrome finish provides corrosion resistance for tools stored in service vans or shop drawers. All six wrenches store in an included tray for organized access. This set is a staple for HVAC technicians, automotive service techs, and plumbers handling flare-type fittings.

Flare nut wrenches are the correct tool wherever a standard open-end wrench risks rounding a fitting — brake lines, fuel lines, refrigerant line sets, gas connections, and hydraulic tubing. The 81907 covers six common SAE inch sizes in one set: 1/4 x 5/16 inches, 3/8 x 7/16 inches, 1/2 x 9/16 inches, 5/8 x 11/16 inches, 5/8 x 3/4 inches, and 3/4 x 7/8 inches. These sizes align with common fitting sizes found on residential and light commercial HVAC equipment, automotive brake and fuel systems, and plumbing supply lines.

Installation Notes

Flare nut wrenches should be used in place of open-end wrenches any time a line fitting must be torqued or broken loose to avoid deforming the fitting hex. Always depressurize or evacuate the relevant system before loosening refrigerant, fuel, or brake line connections in accordance with applicable codes and safety procedures. Confirm the correct wrench size is fully seated on the fitting before applying force to prevent jaw slip.
