Gearwrench 89101D Flare Nut Wrench Set 6 Pc Metric

Product Description

The GEARWRENCH 89101D is a 6-piece metric flare nut wrench set designed for loosening and tightening tube fittings, brake lines, fuel lines, and refrigerant line connections without rounding off the nut. Each wrench features a flexible head that allows access in tight or angled spaces where a straight wrench cannot reach. The set is chrome-plated steel for corrosion resistance and comes organized in a storage tray. HVAC technicians, automotive mechanics, and plumbers reach for this type of set when working with soft metal fittings that standard open-end wrenches tend to damage.

This set is suited for residential and light commercial applications involving refrigerant line fittings, fuel and brake line service, and hydraulic or pneumatic tubing connections. The six metric sizes cover the most common tube nut dimensions found on import vehicles and metric-spec HVAC and refrigeration equipment. The flexible head design extends the usable range of each wrench in confined installation environments such as under dashes, behind equipment panels, and in mechanical rooms.

Compatibility

Designed for use with metric tube fittings and flare nuts commonly found on import vehicles, metric-spec HVAC equipment, and refrigeration line connections requiring metric wrench sizes.

Installation Notes

This set is used by HVAC technicians, plumbers, and automotive mechanics servicing line fittings under pressure. Always depressurize and properly recover refrigerant or fluid from any line before breaking a fitting. Slide the wrench over the tubing before connecting fittings whenever possible, as flare nut wrenches cannot be installed once the line is already made up. Follow applicable service codes and manufacturer procedures when working on refrigerant, fuel, or hydraulic systems.
