Apex 81682 Flare Nut Wrench 1/2 X 9/16 Inch Chrome

Product Description

The APEX 81682 is a double-end flare nut wrench sized at 1/2 inch and 9/16 inch, built for loosening and tightening hex nuts on tubing connections. Manufactured from alloy steel with a full polish chrome finish, this wrench is designed for work on fuel lines, brake lines, and other hydraulic or fluid tubing where a standard open-end wrench risks rounding the nut. Two sizes on a single wrench reduces the number of tools needed on the job. At 0.26 pounds and 7.035 inches in length, it fits easily in a tool roll or service bag. It suits HVAC, plumbing, and automotive service work where flare fittings and tube nuts are common.

This wrench is suited for residential and light commercial service applications where tube connections must be broken or secured without damaging the fitting. Common use cases include refrigerant line service, fuel and brake line repair, and compression fitting work on copper or steel tubing. The enclosed jaw design grips hex nuts on both sides to reduce cam-out, making it a practical choice whenever a tube or line prevents a box-end wrench from seating fully over the fastener.

Key Features

• Two sizes on one wrench: 1/2 inch and 9/16 inch
• Enclosed flare nut jaw grips hex nuts where tubing is present
• Alloy steel construction for durability under torque
• Full polish chrome finish resists corrosion and simplifies cleaning
• Compact at 7.035 inches long and 0.26 pounds

Compatibility

Designed as a standard-pattern flare nut wrench for 1/2 inch and 9/16 inch hex nuts commonly found on fuel lines, brake lines, refrigerant tubing, and compression fittings in HVAC, plumbing, and automotive service.

Installation Notes

Always depressurize or shut off the fluid system before breaking a flare nut connection. Position the wrench fully over the nut before applying force to prevent rounding. Use in conjunction with a backup wrench on the mating fitting when working on live tubing to prevent twisting the line. Technicians should follow applicable codes and manufacturer torque guidance for the specific fitting type being serviced.
