Williams Comfort Products XFN-2836-TH Flare Nut Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS XFN-2836-TH is a flare nut wrench sized for 7/8 inch and 1-1/8 inch fittings. Also known as a line wrench or crowfoot wrench, this tool is designed to grip tubing nuts and flare fittings with maximum contact surface, reducing the risk of rounding corners on soft fittings. It is a standard hand tool for HVAC technicians, refrigeration mechanics, and plumbers working on refrigerant lines, fuel lines, and hydraulic connections where open-end wrenches lack the grip needed to seat or break loose a flare nut safely.

This wrench is used wherever flare-type fittings are present, including residential and light commercial HVAC refrigerant line sets, fuel oil supply lines, and plumbing supply connections. The two jaw sizes, 7/8 inch and 1-1/8 inch, cover common flare nut sizes encountered on copper tubing connections in HVAC and refrigeration applications. It is sold as a single unit and is suited for bench use or field service kits.

• Flare nut profile grips across multiple flats for reduced fitting damage
• Dual-size jaw openings: 7/8 inch and 1-1/8 inch
• Designed for use on refrigerant lines, fuel lines, and hydraulic tubing fittings

Compatibility

Designed as a general-purpose flare nut wrench suitable for common 7/8 inch and 1-1/8 inch flare fittings found on HVAC refrigerant line sets, fuel oil lines, and plumbing supply connections.

Installation Notes

This tool is used by licensed HVAC technicians, refrigeration mechanics, and plumbers during service or installation of flare-type fittings. Always isolate and recover refrigerant before disconnecting refrigerant-side fittings in accordance with EPA Section 608 requirements. Shut off fuel supply or water supply before breaking line connections. Use the correct jaw size to avoid slipping and damaging the fitting.
