Scott Posted February 17, 2012 Author Share Posted February 17, 2012 Should be visually obvious if its a taper thread It's easy to spot the male side of things but with an approx 8mm hole it's quite difficult to tell. Link to comment Share on other sites More sharing options...
Dnk Posted February 17, 2012 Share Posted February 17, 2012 Do you have any drill sets at home, just get the drill thats fits the hole at the bottom of the thread and then it will be obvious if the front of the thread is bigger Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 17, 2012 Share Posted February 17, 2012 NPT and BSP are very similar in taper form, but one will not go far into the other. My guess is the thread is NPT or BSP taper. Link to comment Share on other sites More sharing options...

Hoping so, I've ordered a BSP taper bung type thing. I think the stock intake temp sensor is NPTT so I'm ruling that out for now. Link to comment Share on other sites More sharing options...
Dnk Posted February 17, 2012 Share Posted February 17, 2012 Well yes the vernier would be better but the drill will give you a visual as to whether it is tapered or not which it looks like it is. If it is NPT and close to 10 mm then its only going to be 1 size which is 1/8 NPT which has a tapping drill size of letter Q or 0.332" 1/4 NPT has 7/16 tapping drill size (0.438") and 1/16 NPT is letter C or 0.242" Link to comment Share on other sites More sharing options...
