Understanding pipe threads types and designations

Pipe thread sizes are based on an inside diameter ID or flow size For example 1 2–14 NPT identifies a pipe thread with a nominal inside diameter of 1 2 inch and 14 threads to the inch made according to the NPT standard If LH is added the pipe has a left hand thread The most common cpcworldwide com Page 2 global pipe thread forms are NPT American Standard
