Williams JHW10718 Open End Crowfoot Wrench 1-1/2 in

Product Description

The WILLIAMS JHW10718 is a 1-1/2 inch open end crowfoot wrench designed for use with a 3/8 inch drive ratchet or torque wrench. It gives technicians access to fasteners and fittings in confined spaces where a standard box or open end wrench cannot swing a full arc. Constructed from steel with a high-polished chrome finish, this 6-point crowfoot head measures 2.5 inches in head diameter and 0.375 inches in head thickness. The overall tool length is 2.5 inches. At 0.26 pounds, it is light enough to carry in a standard tool pouch without adding significant weight.

This crowfoot wrench is well suited for HVAC, plumbing, and mechanical service work where access to 1-1/2 inch fittings, nuts, or unions is restricted by surrounding components. Common applications include tightening refrigerant line fittings, plumbing union nuts, and hydraulic or gas line connections where a conventional wrench cannot seat properly. It pairs with any standard 3/8 inch drive ratchet, extension, or torque wrench, allowing accurate torque application in tight quarters. Sold individually, it is a targeted addition to a service technician tool set rather than a general-purpose purchase.

Key Features

• 1-1/2 inch open end jaw fits hex fittings and nuts of that size
• 3/8 inch square drive accepts standard ratchets, extensions, and torque wrenches
• 6-point head geometry distributes load evenly and reduces fastener rounding
• High-polished chrome finish resists corrosion and simplifies cleaning
• Compact 2.5 inch overall length allows use in restricted access areas
• Steel construction provides durability under normal service torque loads

Compatibility

Designed as a standard 3/8 inch drive crowfoot wrench compatible with any 3/8 inch drive ratchet, torque wrench, or extension bar used in professional mechanical, HVAC, and plumbing service applications.

Installation Notes

This tool is installed by qualified tradespeople including HVAC technicians, plumbers, and mechanical service professionals. Before servicing any fitting or connection, shut off and isolate the relevant system — whether refrigerant, gas, or water — and relieve system pressure per applicable codes and safety procedures. When using this crowfoot with a torque wrench, account for any offset angle between the drive centerline and the wrench jaw centerline, as this affects the effective torque applied to the fastener. Do not use extensions or adaptors that introduce play or misalignment beyond the designed drive connection.
