Williams Comfort Products BCF24 Crowfoot Flare Nut Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS BCF24 is a 3/8 inch drive crowfoot flare nut wrench sized at 3/4 inch, built for controlled torque applications where a standard socket or open-end wrench cannot reach. Crowfoot flare nut wrenches wrap around the flats of a fitting rather than gripping just two sides, reducing the risk of rounding soft flare fittings on refrigerant lines, fuel lines, and hydraulic connections. At 0.16 pounds, this wrench is a lightweight addition to a service kit. It is designed for use with any standard 3/8 inch drive torque wrench or ratchet extension.

This tool is well-suited for HVAC technicians, plumbers, and refrigeration mechanics working in confined spaces where a full-body wrench cannot swing freely. Common applications include tightening or loosening flare nut fittings on copper refrigerant lines, fuel supply connections, and hydraulic fittings in residential and light commercial equipment. The crowfoot design allows the drive tool to be offset from the fitting, making it useful when access is restricted by panels, adjacent components, or structural framing.

Compatibility

Installation Notes

Licensed HVAC technicians and plumbers are the typical users of crowfoot flare nut wrenches during line set connections and service valve work. Always de-energize and isolate the system before working on refrigerant or fuel fittings. When using this wrench on a torque wrench, account for any offset distance to apply a corrected torque value per the fitting manufacturer's specification. Do not use with impact drivers.
