Fuel Line Union Nut Socket Set, 14-Piece — 8-22mm, 3/8"/1/2" Drive

Break loose fuel and brake line union nuts without rounding them. This 14-piece open-end socket set covers 8 to 22mm across 3/8 and 1/2 inch drive, sized to grip flare nuts on fuel lines, ABS lines, master cylinder lines and diesel injection pipes.

Why you need it

Standard sockets cannot get over a line, and an open-end wrench rounds a tight flare nut. An open-end socket slides over the line and grips all the flats.
