    Default That flexible metal conduit?

    Looking for that small diameter flexible metal wire conduit,the type that shows up on DRO's and other things electronic that's intended to work with metric multi-pin connectors like these-

    Looking for sizing/dimension info and industry nomenclature.I have the connectors,but I am at a loss finding the conduit.
    I just need one more tool,just one!

    I searched "miniature flex conduit" and this popped up. Sizes down to 3.5mm.

    Comedy aside, When I was an apprentice electrical engineer, we worked on many factories and mills, and installed miles of the stuff, the larger diameters, say 1"+ were known by the lads as "'oss cock" all very amusing till a new boy, thinking that Osscock was a trade name, booked it down on a materials sheet booked out to a job. Harsh words were said..............................

    There are many varieties of the flexible conduit and some will be available at your local lumber supply. But, having worked in electronics for many years and having used the cheap, consumer style connectors you show, I do not think that any of the flexible conduits are "designed" to work with them. Yes, products are made with these products. But I am afraid that you will have to do the design engineering if you want to fit the two together.

    You might try contacting the manufacturers of the connectors.

    Make it fit.

    For standard Metallic (and non-metallic) flexible conduit there is connector/adapters made for the various military style MS connectors and are made by T&B.
    But these generally do not go down as small as the OP might need.

    You might be surprised how easy it is to make an adapter if you own a bit of bar stock and a lathe.

    The best source for the type of flex I think you want will come from thermocouple or RTD suppliers. They can supply anything from 3/16" diameter flex up to 3/8". 1/4" is kind of standard for a three wire RTD's, and most all of their offerings will be stainless. Here's a quick one I called up, but there are many others:

    Copex seems common over here, I like the plastic covered myself, Cincinnati used green hose pipe on many mills (1/2") I discovered

    The Thermocouple stuff looks to be the one that most closely resembles what I am looking for.I figured since the Chinese make the connectors and they use the stuff on their DRO scale leads,then surely they also make it too,but China direct website search terms are less than prescise LOL
