Gearwrench 81906 Flare Nut Wrench Set 6 Pc Metric

Product Description

The GEARWRENCH 81906 is a 6-piece metric flare nut wrench set designed for technicians working on fuel, brake, and refrigerant line fittings where standard open-end wrenches risk rounding soft tubing nuts. Each wrench features a 6-point, 15-degree offset head that provides better knuckle clearance in tight spaces while maximizing contact on hex fittings. The polished finish resists corrosion in shop and field environments. The set arrives in a storage tray that keeps sizes organized and accounts for every piece at a glance. This set is built for HVAC, automotive, and plumbing professionals who regularly service line fittings.

Flare nut wrenches are the correct tool for service work on threaded tubing connections found in refrigerant lines, hydraulic brake lines, fuel systems, and compression fitting assemblies. The enclosed head design grips five of the six flats on a tubing nut, spreading load across the fitting and reducing the chance of rounding. This set covers the most common metric sizes encountered in residential and light commercial HVAC service, automotive brake and fuel line repair, and plumbing compression fitting work. The storage tray keeps the full set accessible on a service vehicle or shop bench.

Designed for use on metric flare and tubing nuts commonly found in HVAC refrigerant lines, automotive brake and fuel lines, and plumbing compression fittings requiring sizes from 9 mm through 21 mm.

Installation Notes

Always shut off system pressure and depressurize lines before loosening any tubing fittings. A licensed HVAC technician, mechanic, or plumber should perform work on pressurized refrigerant, fuel, or brake line systems in accordance with applicable codes and regulations. Use the correctly sized wrench for each fitting to avoid distorting the nut. Do not use extensions or cheater bars on flare nut wrenches, as this can crack the enclosed head or damage the fitting.
