Gearwrench 89118 11 Pc 3/8 Drive Crowfoot Wrench Set

Product Description

The GEARWRENCH 89118 is an 11-piece, 3/8 inch drive open end crowfoot wrench set covering fractional sizes from 3/8 inch through 1 inch. Crowfoot wrenches attach directly to a 3/8 inch drive ratchet or extension, giving technicians access to fasteners and fittings in tight spaces where standard open-end wrenches cannot reach. The set is constructed from steel with a corrosion-resistant finish and meets or exceeds ASME standards. It is a practical addition to any professional tool kit where plumbing, HVAC, or mechanical work demands reach into confined areas around pipes, fittings, and line connections.

This set is suited for residential and light commercial service work. HVAC technicians use crowfoot sets when tightening or loosening refrigerant line fittings, flare nuts, and service valve packing nuts. Plumbers reach for them around supply stops, angle valves, and compression fittings in tight cabinet spaces. The 11 fractional sizes in this set cover the most common inch-size fasteners encountered in those applications, reducing the need to carry multiple individual crowfoot wrenches on a service call.

Key Features

• 11-piece set covers 3/8 inch through 1 inch in fractional increments
• 3/8 inch square drive opening fits standard ratchets, extensions, and torque wrenches
• Open end crowfoot design accesses flats on fittings and fasteners in restricted spaces

Compatibility

Designed for use with any 3/8 inch square drive ratchet, breaker bar, extension, or torque wrench. Compatible with standard inch-size fasteners and fittings from 3/8 inch through 1 inch.

Installation Notes

Crowfoot wrenches are installed by a licensed mechanic, HVAC technician, or plumber as part of routine service and repair. Always de-energize equipment and shut off fluid supply or refrigerant service valves before loosening or tightening fittings. Ensure the crowfoot is fully seated on the fastener flats before applying torque to prevent rounding. Follow applicable codes and manufacturer guidelines for final torque requirements on the specific fitting or fastener being serviced.
