NPT - National Pipe Thread Taper

Note! Pipe thread sizes do not refer to any physical dimensions. The outside diameter of a pipe or fitting must be measured and referenced to a table for size identification.

Note! Inserting a NPT tapered fitting into a port tapped for a straight thread fitting and tightening it can break or severely damage the item the fitting is being installed in.
