Milwaukee Tool 45-96-8301 Flare Nut Wrench 3/8x7/16 in

Product Description

The MILWAUKEE TOOL 45-96-8301 is a double-end, 6-point flare nut wrench sized 3/8 inch by 7/16 inch, built for technicians working on refrigerant lines, fuel lines, and hydraulic fittings. The enclosed flare-nut head wraps around the fitting on five sides, reducing the risk of rounding soft brass or steel flare nuts during torquing. Constructed from chrome-finished steel, it measures 6.46 inches in overall length with a straight head and a head thickness of 0.335 inches. This wrench is a standard hand tool for HVAC technicians, plumbers, and refrigeration mechanics who regularly service flared tubing connections.

This wrench is suited for residential and light commercial service work where 3/8-inch and 7/16-inch flare fittings are common — including refrigerant line sets, gas supply connections, and brake or fuel lines. The double-end configuration gives technicians two sizes in a single tool, reducing the number of wrenches needed in a tight mechanical space. The corrosion-resistant chrome finish holds up in wet or humid service environments typical of HVAC and plumbing applications.

Key Features

• Double-end design covers both 3/8-inch and 7/16-inch flare fittings in one tool
• 6-point flare nut opening grips five sides of the fitting to reduce rounding
• Straight head with zero offset angle for direct access to inline fittings
• Chrome-finished steel construction provides corrosion resistance
• Compact 6.46-inch overall length fits in tight mechanical spaces
• Lightweight at 0.24 pounds for extended service work without fatigue

Compatibility

Designed for use with standard 3/8-inch and 7/16-inch flare nut fittings found on refrigerant line sets, gas supply lines, and other flared tubing connections in HVAC, plumbing, and refrigeration systems.

Installation Notes

This wrench is used by licensed HVAC technicians, refrigeration mechanics, and plumbers during flare fitting service and installation. Always isolate and depressurize the line before loosening or tightening flare fittings. Position the wrench fully onto the nut before applying force to avoid slipping and fitting damage. Follow applicable codes such as IFGC for gas line work and manufacturer torque guidance for refrigerant flare connections.
