Ridgid Tools 37040 Die Head 1/2 Inch Npt 11-R Threader

Product Description

The RIDGID TOOLS 37040 is a replacement die head designed for cutting 1/2 inch NPT right-hand threads on pipe. Built for the 11-R manual pipe threader series, this die head uses alloy steel dies to deliver consistent, clean thread cuts on steel and iron pipe. Licensed plumbers and pipefitters reach for this die head when performing field threading without a powered threading machine. The alloy steel construction holds cutting edges through repeated use and resists the wear that comes with regular job-site threading work.

This die head is suited for residential and commercial plumbing applications where manual pipe threading is required. It is sized for 1/2 inch nominal pipe and cuts NPT threads, making it appropriate for water supply lines, gas piping, and general mechanical piping installations where threaded connections are specified. Manual threading with the 11-R is common in tight spaces or remote locations where a power threader cannot be used.

Key Features

• Cuts 1/2 inch NPT right-hand threads to standard pipe thread specifications
• Alloy steel die material for durable cutting performance under field conditions
• Designed specifically for use with Ridgid 11-R Manual Pipe Threaders
• Right-hand thread direction matches standard NPT plumbing and gas piping requirements
• Drop-in replacement die head for compatible 11-R threader bodies

Compatibility

Installation Notes

Die head installation and pipe threading should be performed by a licensed plumber or qualified pipefitter. Before threading, ensure the pipe is properly secured in a vise and that cutting oil is applied to reduce heat and extend die life. Inspect the die head for damage or worn cutting edges before each use. Follow applicable local plumbing and mechanical codes when making threaded pipe connections.
