    Hi. I have an old Yanmar engine that has oil pressure switch with ISO 7-1 (alias JIS B0203, DIN 2999, BS21) thread. I want to add a sensor for oil press gauge but that has NPT 1/8. Where can I get an adaptor with one male ISO, one female ISO and one female NPT? Can't find anything on the internet. It can be a T-piece, etc. Who does them? Where can I go?

    Do common plumbers make such pressure threads? As the engine has external oilways, there is a possibility to solder a small chamber with threaded hole somewhere else than original.

    Marine parts shop was no help. Is it financially viable to get a taper, get a small piece of brass/copper pipe and do it myself? How to do it, where to get the tools, where the blank T-piece?

    Thanks for all answers, after about a month of intensive search I have found absolutely nothing!
