Williams Comfort Products JHW10656 Flare Nut Wrench Metric

Product Description

The WILLIAMS COMFORT PRODUCTS JHW10656 is a metric flare nut wrench designed for use on flare fittings found on refrigerant lines, gas tubing, and hydraulic connections. With a 15 mm by 17 mm opening and an overall length of 7.875 inches, this wrench provides controlled torque on soft fittings without rounding or crushing the nut. The satin-chrome textured finish improves grip in oily or wet hands. Recessed corners in the box ends engage more of the fastener surface, delivering additional turning power on stubborn or corroded fittings. Licensed HVAC technicians and plumbers working on tubing connections are the primary users of this tool.

This wrench is suited for metric flare fittings on refrigerant piping, gas supply lines, and other soft-metal tubing assemblies in both residential and light commercial service environments. The 15 mm by 17 mm sizing covers common metric flare nut sizes encountered on mini-split lineset connections, gas appliance flex connectors, and similar tubing applications. Its compact 7.875-inch overall length allows use in moderately tight service spaces. It is sold as a single piece and is appropriate for field service kits or shop tool sets.

Installation Notes

This tool is used by licensed HVAC technicians and plumbers when connecting or disconnecting flare fittings on refrigerant or gas lines. Always isolate and recover refrigerant or shut off gas supply before loosening flare connections. Use a backup wrench on the opposing fitting body to prevent tubing from rotating or kinking. Do not use extension bars or cheater pipes on this wrench, as over-torquing flare fittings can cause leaks or fitting failure.
