Carlyle 9mm x 11mm Flare Nut Wrench (CFNW911M)

Description

Genuine Carlyle · Part no. CFNW911M

Carlyle's CFNW911M is a flare nut spanner with a 9mm end and an 11mm end, both thick 6-point jaws with a slot for the pipe. 11mm is the hex on brake pipe nuts on many cars, and the jaw wraps round most of the nut, so a soft union is far less likely to round off. Both ends offset 15 degrees; packed length 151 mm.

Good to know

• Why not use an ordinary 11mm spanner on brake pipes? An open jaw holds only two flats, and pipe nuts are soft and often corroded, so it rounds them. This grips the nut on most of its sides.
• How do I undo a union without twisting the pipe? Soak it with penetrating oil, then hold the body of the fitting still with a second spanner while you turn the nut.
• What do I need to do after opening a brake line? Bleed the brakes before the car is driven, and never drive with a soft pedal. Cover paintwork, as brake fluid damages it.
