Eagle Cutting Tool NHD-3750-18-I Npt Pipe Hex Die 3/8-18

Product Description

The EAGLE CUTTING TOOL NHD-3750-18-I is a carbon steel hex pipe die sized for 3/8-18 NPT threading. It cuts National Pipe Taper threads on pipe and fittings in the 3/8-inch nominal size at 18 threads per inch. The hex body seats into standard die stocks and threading handles used by plumbers, pipefitters, and mechanical contractors. Weighing 0.37 pounds, it is a compact, single-die replacement or addition to a threading set. This die is sourced as an import-grade tool suited for general-purpose pipe threading where high-volume production tooling is not required.

This die is used in plumbing, pipefitting, and HVAC piping applications where field-cut NPT threads are needed on 3/8-inch pipe. Typical scenarios include threading new pipe runs, recutting damaged threads, or extending existing systems. It is appropriate for residential and light commercial work involving steel or iron pipe.

Installation Notes

Pipe dies of this type are installed and operated by licensed plumbers or pipefitters following applicable IPC and IFGC guidelines. Ensure the die stock is properly sized for a hex die body before seating the die. Apply cutting oil generously during threading to extend die life and produce clean thread form. Inspect cut threads with a NPT thread gauge before assembly to confirm proper taper and fit.
