Williams Comfort Products XFN-1214-TH Flare Nut Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS XFN-1214-TH is a flare nut wrench sized to fit 3/8-inch and 7/16-inch fittings. Flare nut wrenches, also called line wrenches or crow-foot wrenches, grip around the flats of a tube nut rather than at two points like an open-end wrench. This design reduces the risk of rounding the nut during tightening or loosening, which matters when working on refrigerant lines, fuel lines, or brake lines. HVAC technicians, plumbers, and automotive service professionals reach for this style of wrench when servicing flared tubing connections in confined spaces. The XFN-1214-TH weighs 0.14 pounds, making it a lightweight addition to a service bag or tool roll.

This wrench is suited to work on flared tubing connections found in residential and light commercial HVAC systems, refrigeration lines, and plumbing supply runs. The dual-size head covers both 3/8-inch and 7/16-inch fittings, reducing the number of individual tools needed when working on systems that use both sizes. It is commonly used when connecting or disconnecting refrigerant line sets, replacing service valves, or servicing flare fittings on gas appliances and copper tubing assemblies.

Key Features

• Fits 3/8-inch and 7/16-inch flare nut fittings in a single tool
• Flare nut profile grips more flats than an open-end wrench, reducing nut damage
• Lightweight at 0.14 pounds for easy carry in a service bag
• Dual-end design covers two common fitting sizes used in HVAC and plumbing

Compatibility

Designed for use on 3/8-inch and 7/16-inch flare nut fittings commonly found on copper tubing, refrigerant line sets, and flared gas or plumbing connections.

Installation Notes

A licensed HVAC technician or plumber should recover or isolate refrigerant and shut off any gas or water supply before loosening flare fittings. Flare nut wrenches are hand tools and do not require power; apply steady, controlled torque to avoid distorting the flare seat. Always inspect the flare for damage before reinstalling the fitting nut.
