Quick Q! Bleed nipple mm size

[jamlid]

Just a quick question as I need to buy a flare spanner tomorrow..

What size in mm is the bleed nipple on the clutch slave cylinder?

Googled and searched but couldn't find an answer (and don't have time to get under the car!)


Thanks

Its 7mm, but why do you need a flare nut spanner, you can get any open ended, ring spanner or even some sockets to the nipple?

I guess because they are made of cheese and prone to rounding. Get plenty of WD40 on it the day before, and if it looks really bad give it a minute blast of a heat gun. Works wonders!
