WARNING!

Always determine if NPT or
NPTF profile should be used.
Be sure you use the right one!


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.
