The Ridgid 37400 is a 12-R (NPT) die head, model number 12-R: (NPT), built for use with compatible Ridgid pipe threading machines to produce accurate National Pipe Thread (NPT) profiles on pipe and conduit. This die head is available in a range of sizes from 1" through 2" (1", 1-1/4", 1-1/2", and 2"), allowing shops and field crews to select the correct size for their specific threading job while relying on the same 12-R NPT profile design across the family.
