Williams Comfort Products 10650-TH Flare Nut Wrench 9x11mm

Product Description

The WILLIAMS COMFORT PRODUCTS 10650-TH is a flare nut wrench sized for 9mm and 11mm fittings. Flare nut wrenches, also called line wrenches or tubing wrenches, are designed with an open slot that allows the wrench to slide over a brake line, fuel line, or refrigerant tubing before engaging the fitting hex. This design provides more contact area than a standard open-end wrench, reducing the risk of rounding soft flare nut fittings. The 10650-TH is a single-piece hand tool sold individually and weighs 0.11 pounds, making it a compact addition to a service bag or tool kit.

This wrench is suited for HVAC technicians, plumbers, and refrigeration service pros who work with flared tubing connections on copper or aluminum lines. Typical applications include tightening or loosening refrigerant line fittings, fuel line connections, and hydraulic or brake line nuts where a standard open-end wrench risks slipping. The 9mm and 11mm sizing covers common metric fitting sizes encountered in residential and light commercial service work.

Key Features

• Flare nut profile contacts more of the hex than a standard open-end wrench, reducing fitting damage
• Open slot design allows wrench to slide over tubing before seating on the fitting
• Dual-size head fits both 9mm and 11mm flare nuts in one tool
• Lightweight at 0.11 pounds for easy one-handed use in tight access areas
• Sold individually with a minimum order quantity of one

Compatibility

Designed for use with metric flare nut fittings in the 9mm and 11mm size range, commonly found on refrigerant lines, fuel lines, and hydraulic tubing connections in residential and light commercial applications.

Installation Notes

A licensed HVAC technician or qualified plumber should handle flared line connections, particularly on refrigerant circuits subject to EPA Section 608 regulations. Always relieve system pressure and recover refrigerant before disconnecting flared fittings on a charged system. Use the correct size wrench to avoid deforming soft metric fittings, and do not apply excessive torque to flare connections.
