OTC Tools 7304 3/8" x 7/16" Flare Nut Wrench

The OTC Tools 7304 is a professional-grade flare nut wrench designed for working with brake lines, fuel lines, and other hydraulic fittings. This dual-size wrench features 3/8" and 7/16" openings, covering two of the most common line fitting sizes found in automotive applications.

Key Features:

• Dual-size design with 3/8" and 7/16" flare nut openings
• Six-point box-end configuration provides superior grip and reduces rounding of fasteners
• Open-end design allows wrench to slide over brake and fuel lines
• Forged construction for strength and durability
• Chrome finish resists corrosion and is easy to clean

Flare nut wrenches are essential tools for brake system service, fuel system repairs, and hydraulic line work. The box-end design surrounds five sides of the fitting, distributing force more evenly than standard open-end wrenches while still allowing the tool to slip over the line. This professional-quality wrench from OTC Tools is built to withstand the demands of daily shop use.
