    Just found this

    But it seems a bit long, if the 1/8" npt female thread is cut all the way through might be able to reduce the length!

    7/16 unf bolt cut down with the head tapped to take the 1/8 npt fitting. Would that work.

    Try RS Components, albeit you will get cheaper elsewhere. Any tubing or industrial instrument calibration shop should be able to provide if you have one locally.

    Swagelok and Parkers are the brands I'm familiar with from back in the day working with that sort of stuff. Hydrasun would be another option but not sure if they would do a single reducer.

    Thanks guys, yes I could cut a 1/2" unf bolt down and drill and tap 1/8 npt. But the cost of a drill and tap makes it prohibitive.
    Would rather try and find one.
    Cheers Clive

    Clive I can lend you a 1/8 npt tap if required.
    Tapping drill is 8.5mm (close enough).

    Yep that's the one I've seen . My sump drain angles slightly down and the longer the sensor is protruding the lower it gets! Don't want it removed on a road hump. So if stuck I'll chop it down and recut the internal thread if required. Cheers Clive
