Milwaukee Tool 49-57-5392 Hex Pipe Conduit Die 3/8-18 Npt

Product Description

The MILWAUKEE TOOL 49-57-5392 is a hex pipe conduit die designed for cutting right-hand NPT threads on pipe and conduit. Manufactured from carbon steel, this die produces a 3/8-18 NPT thread profile, the standard taper pipe thread used throughout plumbing and conduit work. The hex body measures 2-1/6 inches across and sits at 3/4 inch thick, fitting standard hex die stocks and pipe threading machines. It is a single-die replacement unit, sold individually, and is suited for pipe mechanics, plumbers, and electricians who need to rethread or replace worn dies in their existing threading equipment.

This die is used in applications where 3/8-inch NPT pipe threads are required, including low-pressure gas piping, water supply lines, and electrical conduit assemblies. It is a fit for shop threading machines and handheld die stocks that accept hex-body dies. Residential and light commercial trade work are the primary install environments, though the die performs in any setting where NPT-threaded 3/8-inch connections are part of the scope of work.

Installation Notes

Installation of pipe threading dies should be performed by a qualified plumber, pipefitter, or electrician familiar with threading equipment. Ensure the threading machine or die stock is fully de-energized and unpowered before removing or seating any die. Secure the die firmly in the stock before applying cutting oil and beginning the thread cut. Follow applicable IFGC and IPC requirements when threading pipe for gas or water service.
