Apex 81646 Flare Nut Wrench 13MM X 14MM Chrome

Product Description

The APEX 81646 is a double-end flare nut wrench sized 13MM x 14MM, built for loosening and tightening hex nuts on tubing connections such as fuel lines and brake lines. Manufactured from alloy steel with a full polish chrome finish, this standard-pattern wrench provides the enclosed-end geometry needed to grip hex nuts without slipping off tubing. At 7.035 inches in length and 0.29 pounds, it is compact enough for tight underhood spaces while still delivering adequate leverage for stubborn fittings. A single wrench covers two common metric sizes, reducing the number of tools needed on the job.

This wrench is suited for use on hex fittings wherever tubing passes through the nut, a common configuration in automotive fuel and brake systems, HVAC refrigerant line sets, and plumbing compression fittings. The flare nut opening allows the wrench to pass over the tube and seat fully on the hex before applying torque, minimizing the risk of rounding soft fittings. Technicians working on metric-dimensioned systems will find the 13MM and 14MM sizes cover frequently encountered fitting sizes in a single tool.

Key Features

• Double-end design: 13MM on one end, 14MM on the other
• Flare nut geometry seats fully on hex for reduced fitting damage
• Alloy steel construction for durability under high torque
• Full polish chrome finish resists corrosion and cleans easily
• Standard pattern body at 7.035 inches overall length
• Lightweight at 0.29 pounds for extended use without fatigue

Compatibility

Designed for use on 13MM and 14MM hex flare nuts where tubing is present, including automotive fuel and brake line fittings and similar tubing connections requiring a flare nut wrench.

Installation Notes

Relieve system pressure and shut off fluid supply before loosening any line fitting. Seat the wrench fully on the hex before applying torque to avoid rounding the fitting. Automotive technicians and plumbers working on compression or flare fittings should follow applicable safety procedures for the fluid system being serviced.
