M3F Posted September 27, 2023 Share Posted September 27, 2023 So I understand it's a 3/8" hole. I checked with a tap and it seems to be M10 x 1.25. My question is how does that convert to NPT? Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted September 27, 2023 Share Posted September 27, 2023 1/8 npt is almost 10x1.0. Pipe thread is tapered, 10x1.0 is straight. Don't make it a hurdle, it is an oiler!!!! Old machinery in North America was not metric. Neil Quote Link to comment Share on other sites More sharing options...
gewoon ik Posted September 27, 2023 Share Posted September 27, 2023 Most old machinery in europe with regards to pipefittings also not metric. Somebody changed it. You can do the same. Or not. Quote Link to comment Share on other sites More sharing options...
