ST needle threads?

[frank mccune]

       Hello:

        Are the threads on ST needles all the same?  I am attempting tp purchase 4 to be used in the ST G20 nva.

NO  They are  NOT  all the same, there is at least 4 of them, and  NO the do not work in every spraybar

    Hi Randy:

     Thanks for taking the time to reply to my post.

     I have quite a collection of ST nva and I thought that I have seen a different diameter used on the smaller ones compared to the midsize spray bars.  The reason that I asked, was that a couple of "experts" assured me that they all had the same thread size and the only difference was in the length of the needle.

     I ask a lot of questions on this site to help me avoid making poor decisions.  This aids me determining the difference between fact and opinion. 

                                                                                                                Be well,

I've never seen ST needles with different thread pitch and diameter. Maybe Randy means different lengths?

I think there are 5 different length spray bars and some of the needles can cross over to be used in a different spray bar but they don't all interchange.

Yes  I said at least 4 different ones,  Your  right as there maybe  5 or 6,  they are  the same threads,  but  here are some reasons they do not  work, some are very long, some are very short, there is a very short one with a  longer thinner  taper, and  other have slightly different tapers, there is even  ST needles  out there that are  slightly smaller diameter
Some of the long thin tapers from the  11 or 15   will not work in other  spraybars, vise=versa  for the longer ones
