Milwaukee Tool 45-96-8300 Flare Nut Wrench 1/4x5/16 in

Product Description

The Milwaukee Tool 45-96-8300 is a double-end flare nut wrench sized at 1/4 inch and 5/16 inch, built for gripping flare fittings on refrigerant lines, fuel lines, and hydraulic tubing without rounding the nut. The 6-point flare nut opening surrounds five sides of the fitting hex, providing more contact and less slip than a standard open-end wrench. Constructed from chrome steel with a corrosion-resistant finish, the wrench measures 5.04 inches in overall length with a straight head and a head thickness of 0.256 inches. HVAC technicians, plumbers, and fuel-line service pros reach for this tool when working on flare connections in tight spaces where a tubing wrench must stay flat and low-profile.

This wrench is suited for residential and light commercial service work involving refrigerant line sets, copper tubing flare connections, brake lines, and similar small-diameter flared fittings. The 1/4 inch and 5/16 inch openings cover two of the most common flare fitting sizes encountered in HVAC split-system lineset work and plumbing service. Its straight-head, non-offset design keeps it compatible with inline fitting access where angled wrenches would not seat cleanly.

Key Features

• 6-point flare nut opening grips five sides of the fitting hex to reduce rounding on soft brass flare nuts
• Double-end design provides 1/4 inch and 5/16 inch openings in a single tool
• Chrome steel construction with corrosion-resistant finish for service in humid or outdoor environments
• Straight head with 0-degree offset angle for flat, inline fitting access
• Low-profile head thickness of 0.256 inches for access in confined spaces
• Compact 5.04-inch overall length keeps the tool manageable in tight line-set runs

Compatibility

Designed as a general-purpose flare nut wrench for 1/4 inch and 5/16 inch flare fittings commonly found on refrigerant line sets, copper fuel lines, and hydraulic tubing connections.

Installation Notes

A licensed HVAC technician or plumber should recover any refrigerant and relieve system pressure before loosening flare connections. Always confirm the fitting size before applying the wrench to avoid deforming soft brass flare nuts. Do not use extensions or extra leverage on this wrench, as flare fittings require controlled torque to reseat properly. Follow applicable EPA Section 608 requirements when working on refrigerant circuits.
