Apex 81645 Flare Nut Wrench 10MM X 12MM Chrome Standard

Product Description

The APEX 81645 is a standard-pattern flare nut wrench sized 10MM x 12MM, built for loosening and tightening hex nuts where tubing is present. Manufactured from alloy steel with a full polish chrome finish, this wrench provides two sizes in a single tool, reducing the number of pieces a technician needs on the job. The 81645 is suited for brake line fittings, fuel line connections, and similar hydraulic or fluid system work where an open-end wrench risks rounding the nut. At 0.22 pounds and 6.535 inches in length, it fits easily in a tool pouch or roll-up bag.

This wrench is designed for automotive, HVAC, plumbing, and general mechanical applications where tube-and-fitting assemblies require precise torque without damage to the fitting. The enclosed head design grips more of the hex surface than a standard open-end wrench, making it the preferred choice for soft brass or aluminum fittings found on refrigerant lines, brake lines, and fuel supply connections. Licensed technicians and experienced DIYers working on fluid-carrying systems will find it a reliable everyday hand tool.

Key Features

• Standard-pattern body with 10MM and 12MM openings on a single wrench
• Alloy steel construction for durability under high-torque service
• Full polish chrome finish resists corrosion and wipes clean easily
• Enclosed head grips more hex surface to reduce rounding on soft fittings
• Compact 6.535-inch length fits in tight engine bays and equipment cabinets
• Lightweight at 0.22 pounds — minimal added weight to a tool bag

Compatibility

Designed for use on standard hex nuts in tube-and-fitting assemblies, including vehicle fuel lines, brake lines, and similar hydraulic or refrigerant line connections where tubing restricts access for open-end wrenches.

Installation Notes

Always relieve system pressure and isolate the fluid circuit before loosening any fitting on a fuel, brake, or refrigerant line. Select the correct size opening before applying force to avoid rounding the fitting. Hand tools of this type are installed and serviced by automotive technicians, HVAC mechanics, and plumbers working under applicable codes. Inspect the wrench for cracks or deformation before each use and replace if damaged.
