Apex 81647 Flare Nut Wrench 15MM X 17MM Chrome

Product Description

The APEX 81647 is a standard-pattern flare nut wrench sized 15MM x 17MM, designed for loosening and tightening hex nuts where tubing obstructs access to a conventional open-end wrench. Built from alloy steel with a full polish chrome finish, it delivers corrosion resistance and durability in demanding shop and field environments. Each wrench carries two sizes, reducing the number of individual tools needed in a technician's bag. At 0.4 pounds and 7.614 inches in length, it is compact enough for tight underhood spaces without sacrificing leverage. Licensed HVAC techs, plumbers, and automotive technicians reach for this tool when working on fuel lines, brake lines, and refrigerant or hydraulic fittings where tube-clearance is a constraint.

The 81647 is suited for any trade application requiring controlled torque on hex nuts with adjacent tubing. Common use cases include vehicle brake and fuel line service, HVAC refrigerant line connections, and plumbing supply fittings in confined spaces. The standard pattern body keeps the profile low, making it easier to work in areas with limited swing room. Sold individually, it integrates cleanly into an existing flare nut set or works as a standalone replacement for a worn or missing size.

Key Features

• Dual-size wrench — 15MM on one end, 17MM on the other — reduces tool count
• Alloy steel construction for strength under sustained torque
• Full polish chrome finish resists corrosion and simplifies cleanup
• Standard pattern body fits tight clearance areas around tubes and lines
• Compact at 7.614 inches overall length and 0.4 pounds

Compatibility

Designed as an OEM-style replacement or addition for use on 15MM and 17MM hex nuts where tubing is present, including typical automotive fuel and brake line fittings and plumbing or HVAC line connections of the same hex size.

Installation Notes

This wrench is intended for use by licensed technicians and qualified trade professionals working on pressurized fuel, brake, refrigerant, or plumbing lines. Always depressurize and isolate the system before breaking any fitting loose. Use the correctly sized end to avoid rounding the hex. Do not use extensions or cheater bars on a flare nut wrench, as this can distort the wrench opening and damage the fitting.
