Williams Comfort Products 10652-TH Flare Nut Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS 10652-TH is a flare nut wrench sized for 10 MM and 12 MM fasteners. Flare nut wrenches, also called line wrenches or fitting wrenches, are engineered to grip more of a nut's surface than a standard open-end wrench. This reduces the risk of rounding soft fittings found on refrigerant lines, fuel lines, and hydraulic connections. The 10652-TH is a hand tool used by HVAC technicians, plumbers, and mechanics when working on tubing fittings that require controlled torque without damaging the fitting hex.

This wrench is suited for service work on residential and light commercial systems where metric flare fittings are common. Typical applications include refrigerant line connections, brake line fittings, and fuel system tubing. The 10 MM and 12 MM jaw sizes cover a range of metric fasteners frequently encountered in HVAC and plumbing work. Sold individually as a single unit.

Key Features

• Flare nut design grips more fastener surface to reduce rounding on soft fittings
• Dual-size 10 MM and 12 MM heads on a single wrench
• Appropriate for refrigerant lines, fuel lines, and hydraulic tubing connections
• Lightweight at 0.15 pounds for easy one-hand use in tight spaces

Compatibility

Designed for use with metric flare nut fittings in standard 10 MM and 12 MM sizes, as commonly found on HVAC refrigerant tubing, plumbing supply lines, and light mechanical assemblies.

Installation Notes

Flare nut wrenches are installed by HVAC technicians, plumbers, and mechanical trades. Before loosening or tightening refrigerant or fuel line fittings, relieve system pressure and follow all applicable safety procedures. Use the correct jaw size to avoid slipping and damaging the fitting. Consult local codes and manufacturer service manuals for torque requirements on specific fittings.
