Carlyle 10mm x 12mm Flare Nut Wrench (CFNW1012M)

Description

Genuine Carlyle · Part no. CFNW1012M

Carlyle's CFNW1012M is a flare nut (brake pipe) spanner with a 10mm end and a 12mm end. Each end is a thick 6-point jaw with a slot, so it slides over a brake or fuel pipe and closes round the union nut on most of its sides. Both ends sit at a 15 degree offset. Packed length 160 mm.

Good to know

• Why not just use an open-ended spanner on brake pipes? Pipe nuts are soft and often corroded; an open jaw holds only two flats and rounds them, while this wraps round the nut and spreads the load.
• How do I stop the pipe twisting? Hold the body of the fitting still with a second spanner while you turn the union nut, and soak old unions in penetrating oil before trying.
• What happens after I open a brake line? The brakes must be bled before the car is driven, and never drive with a soft pedal. Cover painted panels too, as brake fluid damages paintwork.
• Will 10mm and 12mm suit my car? Measure or try the old union nut first: the jaw should slide on without rocking, because a sloppy fit is what rounds pipe nuts.

Which one?
