Williams Comfort Products XFN-2022-TH Flare Nut Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS XFN-2022-TH is a flare nut wrench sized for 5/8-inch and 11/16-inch fittings. Flare nut wrenches — also called line wrenches or flare wrenches — feature an open slot that allows the tool to slide onto tubing before engaging the fitting hex, while the near-full contact around the nut reduces the risk of rounding soft flare fittings compared to an open-end wrench. This wrench is a standard hand tool used by HVAC technicians and plumbers when servicing refrigerant lines, fuel lines, and hydraulic fittings. It weighs 0.38 pounds, keeping it easy to maneuver in tight equipment bays.

This wrench is suited for residential and light commercial service work wherever 5/8-inch or 11/16-inch flare fittings are present. Common applications include connecting or disconnecting refrigerant line set fittings on split-system air conditioners and heat pumps, fuel line fittings on gas appliances, and brake or hydraulic line fittings. HVAC technicians and plumbers reaching into condensing units, furnace cabinets, or tight mechanical rooms will find the slim profile of a flare nut wrench especially useful where a standard open-end wrench would not seat properly.

Key Features

• Open-slot flare nut design maximizes hex contact to reduce fitting damage on soft copper and brass fittings
• Dual-size head fits 5/8-inch on one end and 11/16-inch on the other, covering two common refrigerant and fuel line fitting sizes in one tool
• Lightweight at 0.38 pounds for easy single-hand use in confined spaces
• Sold individually as a single unit

Compatibility

Designed for use with standard 5/8-inch and 11/16-inch flare fittings commonly found on refrigerant line sets, fuel lines, and hydraulic connections in HVAC and plumbing applications.

Installation Notes

Flare nut wrenches are used by licensed HVAC technicians and plumbers. Before disconnecting any refrigerant fitting, recover refrigerant in accordance with EPA Section 608 regulations. Before disconnecting any fuel line fitting, shut off the gas supply and verify the line is depressurized. Apply steady, controlled torque — do not use extension bars or impact force on flare fittings, as this can crack flared tubing seats.
