NPT Hexagon Re-Threading Die Nuts
Our range of NPT hexagon re-threading die nuts is designed for cleaning and restoring damaged external National Pipe Taper (NPT) threads. These die nuts are used for maintenance and thread repair applications rather than cutting new threads.
NPT threads feature a tapered profile that creates a pressure-tight seal, commonly used in hydraulic, pneumatic and fluid transfer systems, particularly in American and international equipment. The hexagonal form allows use with a standard spanner or socket for controlled thread restoration.
Browse the range below and refine by NPT thread size to find the correct hexagon re-threading die nut for your application.
