Replacement brake bleed nipples ?

[dylanoldspot]

Hi, I need to replace the brake bleed nipples on my 1999 Terrano II 2.7TDi LWB, as the flats were round by the local garage. Had a trawl through the Nissan 4x4 forum, found a reference to the question but no answer.

Can anyone confirm the correct size or a part number to order from a motor factor on the web.

Thanks in advance

Dylan
