    Default British tapered pipe threads (bspt or Rc) chart

    I am looking for a chart showing all the information to turn a bspt thread. Start diameter, and lengths.
    Machinery handbook has 1 page for British pipe threads.

    The metric and multi standard had a chart that showed a picture of the information I am looking for, but it did not tell you what “L1” dimension is equal to.

    The thread data charts, is for bspp, which is a straight pipe thread.
    I am looking for information for a tapered pipe thread.

    Thank all for the help 🤪

    No, it does not tell me the information I am looking for.

    Look at this chart, in the upper right corner. It has a picture with letter depicting certain dimensions. L1, a, c, b,d etc.

    That is the information I am looking for.
