Milwaukee Tool 45-96-8353 Flare Nut Wrench 15x17 Mm

Product Description

The MILWAUKEE TOOL 45-96-8353 is a double-end flare nut wrench sized 15 mm by 17 mm, built for securing and loosening flare fittings on refrigerant lines, brake lines, and fuel lines without rounding the nut. The wrench features a 6-point open-end profile that grips hex flare nuts on two opposing faces, reducing slippage under torque. Constructed from chrome-finished steel, it resists corrosion in the wet and chemically active environments common in HVAC and plumbing service work. The straight head and zero-degree offset angle allow flat access in tight panel and cabinet spaces. At 0.39 pounds, it is light enough for daily carry in a tool pouch.

This wrench is used in residential and light commercial applications wherever flare-nut fittings appear — refrigerant line sets, gas appliance supply connections, hydraulic tubing, and brake line service. HVAC technicians reach for this tool when connecting or disconnecting 15 mm and 17 mm flare fittings during system installation, line-set modification, or component replacement. Plumbers and gas fitters also use this wrench on compression and flare-style gas connectors that share these metric dimensions.

Key Features

• Double-end design provides both 15 mm and 17 mm openings in a single tool
• 6-point flare nut profile grips hex flare nuts firmly and reduces corner rounding
• Chrome-finished steel construction provides corrosion resistance for wet service environments
• Straight head with zero-degree offset angle suits low-clearance fitting access
• Overall length of 7.48 inches delivers practical leverage for hand-tightening and breaking loose fittings
• Non-sparking and insulated ratings not applicable — confirm job-site requirements before use in hazardous locations

Compatibility

Designed for use with 15 mm and 17 mm hex flare nuts on metric flare-type fittings commonly found in HVAC refrigerant line sets, gas appliance supply connections, and hydraulic tubing applications.

Installation Notes

This wrench is typically used by licensed HVAC technicians, plumbers, and gas fitters. Before servicing any refrigerant or gas line, recover refrigerant per EPA Section 608 requirements or shut off and properly purge the gas supply line in accordance with IFGC guidelines. Confirm the fitting size matches the wrench opening before applying torque to avoid rounding the nut. Do not use this tool as a striking wrench or extend the handle with a pipe to increase leverage.
