How to wrap wick on pipe thread

Bing
Bing Member Posts: 6
I am replacing a radiator on a steam heating system with 1-1/4" steel pipe. I want to seal the threads with quick wick and pro dope. What is the procedure to wrap the wick on the threads?
Thank you
Bing

    Do you mean hemp, or the teflon string that Loctite makes?

    With hemp, separate some strands from the bunch and wrap around the male thread, some pipe dope, not much to keep it on the threads.

    The hemp is making the seal, the pipe dope helps glue it to the male thread. The true pros in Europe just use hemp, no dope.

    Here is the hemp they sell in plumbing supply and hardware stores in Europe.

    Think he just means wick @hot rod. I start one strand at the back of the threads, going across all of the threads to the front. Then I begin wrapping it around the threads clock wise.

    Sorry for late response, holiday family prep you know.
    What I'm asking is in line with Danny's comment. I took some pictures (not the best) to hopefully illustrate what I think he is saying. I may be wrong.

    (1) The wick cuts across from back to front of thread.


    (2) Wick wrap groove of thread front to back clockwise


    (3) 1-1/4inch union and ball of wick


    Are the pictures correct, and if they are, is a single winding enough?
    I understand that I should put some dope before and after the wick is wounded on the thread

    Why do you even think you need to use wick on a 1.25" pipe? Dope and tape should be plenty.

    That’s it @bing! Good decoding :wink: now apply some mega lock or whatever pipe sealant you prefer.

    Teflon and pipe dope is good .. Bulding an circulator manifold with quick wick and dope will give you an stiffer structure .. They both have their place ..
    I have enough experience to know , that I dont know it all
