1.) Dimension B is minimum length of perfect thread. The length of useful thread (B plus threads with fully formed roots and flat creates) shall not be less Than L2 (effective length of external thread) required by American National Standard for Pipe Threads (ANSI B2. 1)
Class 2000 and NPS 1/8 class 6000 coupling, half couplings and caps are not included in this standard.
