Performance Tool W30402 3/8" x 7/16" Flare Nut Wrench

The Performance Tool W30402 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, making it ideal for automotive brake system maintenance and repair work where traditional open-end wrenches can round off soft brass or steel line fittings.

Key Features:

• Premium quality drop forged and hardened chrome alloy steel construction for maximum strength and durability
• Flare nut design with 6-point box-end opening provides superior grip while preventing damage to soft fittings
• 15 degree offset head angle allows better access in tight spaces and provides knuckle clearance
• Nickel chrome plated finish resists corrosion and wipes clean easily
• Fully polished surface for professional appearance and easy cleanup
• Dual-size design: 3/8" and 7/16" openings on opposite ends

This flare nut wrench is an essential tool for any mechanic working on brake lines, transmission cooler lines, or fuel system components where preserving fitting integrity is critical. The 6-point design distributes force evenly around the fitting, reducing the risk of rounding corners compared to standard open-end wrenches.
