WARNING! Always determine if NPT or |
 |
NPT and Line Pipe have clearance on the top and bottom of the thread. QuadCut NPT profiles also fit the tolerances for Line Pipe profiles. |
NPTF Dryseal gives a tight fit. This is accomplished when the pipe compo- nents are fitted together, as the top of the thread is deformed by the corress- ponding thread root. |
