These aluminum extenders have male NPT threads at one end and the same size female NPT threads at the other. They are designed specifically to help extend the reach of your NPT fitting, or to get into a restricted space for easier access. Sold individually.
Overall Lengths:
1/8 NPT - 1 1/4" (32mm)
1/4 NPT - 1 1/2" (38mm)
3/8 NPT - 2" (51mm)
1/2 NPT - 2" (51mm)
Note: NPT nomenclature can be confusing because the nominal size refers to the theoretical inside diameter of the pipe, not the outside diameter of the threads. For more information, check out our Guide to Using NPT Fittings.
