Milwaukee Tool 45-96-8351 Flare Nut Wrench 10x12 Mm

Product Description

The MILWAUKEE TOOL 45-96-8351 is a double-end, 6-point flare nut wrench sized at 10 mm and 12 mm. Built from chrome-finished steel, it is designed for gripping flare fittings on refrigerant lines, hydraulic tubing, and fuel lines without rounding the nut. The straight head and zero-degree offset angle allow work in tight spaces where a standard open-end wrench may not seat properly. At 6.46 inches in overall length and 0.22 pounds, it is a compact, lightweight hand tool suited for HVAC technicians, plumbers, and automotive service professionals who regularly work with tubing connections.

This wrench is suited for residential and light commercial service work involving flare fittings on copper refrigerant lines, brake lines, and compression-style tubing connections. The 6-point flare nut opening wraps around more of the fastener than a standard open-end profile, reducing the risk of slippage and fastener damage during tightening or loosening. It is a practical addition to any service kit where metric flare connections in the 10 mm to 12 mm range are common.

Key Features

• Double-end design provides both 10 mm and 12 mm openings in a single tool
• 6-point flare nut opening reduces fastener rounding compared to standard open-end profiles
• Chrome steel construction resists corrosion for long service life in wet or outdoor environments
• Straight head with 0-degree offset angle for direct access to fittings in confined spaces
• Compact 6.46-inch overall length and 0.22-pound weight reduce hand fatigue during extended use

Compatibility

Designed as an OEM-style flare nut wrench for use on metric flare fittings in the 10 mm and 12 mm range, typical of residential and light commercial HVAC, plumbing, and tubing service applications.

Installation Notes

Installation and removal of flare fittings should be performed by a licensed HVAC technician or plumber, following applicable codes such as the IFGC or IPC. Always isolate and depressurize the system before loosening or tightening flare connections. Seat the wrench fully over the nut before applying torque to avoid damaging the fitting. Do not use extensions or additional leverage beyond what the tool handle provides.
