British tapered pipe threads (bspt or Rc) chart

[Yukon Eric]

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.

Try metric and multi standard they have a lot of good information plus good inventory

This site has a ton of info:
Thread Data Charts

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.

All this chart tells me is the major diameter’s
