Thread type for 10mm compression fitting.

[Andy678]

Hi,
Would anyone know what thread type is on a 10mm compression fitting, i.e. the threaded part onto which the compression nut tightens? I need to attach the fitting to a thick aluminium plate (the sump of a small engine) so need to tap a hole to screw the fitting into. From my own measurements it seems to be M14 but I didn't want to purchase a tap only to find it was the wrong sort! If anyone has done this or something similar any information would be very helpful.
Thanks in advance,
Andy

Would it not be easier to use day a 10mm-1/4" male iron? And then just tap a 1/4" hole.

Possibly, though I would prefer the compression fitting as there is limited space. I need the pipe coming off the connector at a right angle, which is much easier to do with only one right angle connector as opposed to a male iron then a right angle connector. That method would work in most situations but here I really do need the right angle connector. But thank you for the suggestion.

He means use one of these

Compression Male Iron Elbow 10mm x 1/4"

Ah right, ok then, that will work! I'll do that. Thank you both.
(By the way, I think the thread type for a 10mm compression fitting is M14 x 1.25 in case anyone else might need to know.)
