Williams Comfort Products JHWXFN-1618 Flare Nut Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHWXFN-1618 is a flare nut wrench designed for use on flare fittings found on refrigerant lines, fuel lines, and other tubing connections where standard open-end wrenches risk rounding off soft fittings. It features a 1/2 x 9/16 inch opening and measures 6-13/16 inches in overall length. The wrench is finished in satin-chrome with a textured surface that improves grip during hand torque. Recessed corners in the wrench ends engage more of the fitting surface to increase turning power while minimizing the risk of marring or deforming the fitting. This tool is suited for HVAC technicians, plumbers, and refrigeration mechanics working on tubing assemblies.

This flare nut wrench is used in residential and light commercial service applications where flare-type fittings are common, including refrigerant line sets, gas supply connections, and hydraulic or fuel tubing. The 1/2 x 9/16 inch dual-size opening makes it practical for a range of common fitting sizes encountered in field service work. It is sold individually and is appropriate for both installation and maintenance tasks requiring controlled, fitting-safe torque.

Key Features

• 1/2 x 9/16 inch flare nut opening fits two common fitting sizes
• Recessed corners engage more fitting surface for increased turning power
• Satin-chrome textured finish improves grip and reduces hand fatigue
• Design minimizes marring on soft flare fittings and tubing connections
• Meets ANSI B107.6 federal specification for flare nut wrenches

Compatibility

Designed for use on standard flare-type fittings with 1/2 inch or 9/16 inch hex profiles, as commonly found on refrigerant, gas, and hydraulic tubing connections.

Installation Notes

This wrench is installed and used by HVAC technicians, plumbers, and refrigeration mechanics. Always recover refrigerant and relieve system pressure before disconnecting flare fittings on refrigerant lines, and shut off gas supply before servicing gas line fittings. Use the correct size opening to avoid slipping and damaging the fitting. Do not use extensions or pipe cheaters on this wrench, as excessive leverage can shear or deform flare fittings.
