Lisle 12030 10-Piece 3/8" Drive Metric Flare Nut Socket Set

The Lisle 12030 is a comprehensive 10-piece metric flare nut socket set designed for working with brake lines, fuel lines, and hard-to-reach sensors. The specialized flare nut design features a six-point opening with a slot that allows the socket to slide over the line while gripping the nut, preventing rounding of soft brass and steel fittings.

Key Features:

• 3/8-inch square drive for use with standard ratchets and extensions
• Chrome-plated finish for corrosion resistance and easy cleaning
• Six-point design provides superior grip and reduces fastener rounding
• Slotted design allows access to flare nuts on brake lines, fuel lines, and transmission cooler lines
• Ideal for working with ABS sensors, master cylinder lines, coolant fittings, and diesel injection components
• Works on temperature sensors, thermo-switches, and other wired components with line connections

Set Includes: 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, and 19mm metric flare nut sockets.

This professional-grade socket set is essential for automotive technicians and DIY mechanics who work with hydraulic brake systems, fuel systems, and pressurized line connections where standard sockets cannot fit over the attached lines.
