Pipe Thread Die 1 1/2 in NPT

The Ridgid 37845 is a four-piece alloy steel die set for cutting right-hand NPT threads on 1 1/2 inch pipe. It works with aluminum or steel pipe and fits Ridgid handheld die heads. The set suits plumbers and maintenance crews who need replacement dies for manual or power threaders.

Suits NPT threading on 1 1/2 in pipe

This set suits users cutting NPT threads on 1 1/2 inch aluminum or steel pipe with compatible Ridgid die heads. It does not suit left-hand thread requirements or pipe sizes other than 1 1/2 inch. Buyers needing different thread forms or diameters should look at other die configurations.

Fits Ridgid 0-R 00-R 11-R 12-R 30A 31A heads

Installation means seating the four dies into a compatible Ridgid die head such as the 0-R, 00-R, 11-R, 12-R, 30A or 31A. The dies lock into the head slots for manual or power threader use. Misalignment in the head slots is the common issue that causes uneven threads.
