Hmm, should be the M12.5 x 1.5 to an 1/8 NPT, pretty sure.

Okay. Just to make sure this is the one your talking about. Cause you keep posting that it is M12.5x1.5 and the part number and link as you can see is M12x1.5 .

 

Good catch, it's M12 x 1.5.... not familiar with an M12.5 haha. The part number is correct, I just mis-labeled it.

 

Ok. Just making sure.
