PERFORMANCE TOOL 9MM X 11MM FLARE NUT WRENCH

When you're working on brake lines or fuel lines, getting a solid grip on those stubborn fittings is key. This 9mm by 11mm flare nut wrench from Performance Tool is designed specifically for those jobs. It's a double-ended wrench, giving you the right size for common fittings you'll encounter on many vehicles.

The flare nut design means the wrench grips the fastener on its flats, not just the corners, which helps prevent rounding off those softer metal fittings. This is especially important when you're dealing with older or corroded lines. Having the correct tool like this makes the job go smoother and helps avoid costly damage to the line itself.
