Rothenberger 00227 NPT Threading Dies
This set provides four high-speed steel dies for cutting NPT threads on pipe from 1/2 in to 3/4 in. They are designed for right-hand threading on alloy, conduit, galvanised steel, iron, stainless steel and steel. The dies fit Rothenberger Snap-O-Matic heads and Collins threading machines. Thread pitch is fixed at 14 threads per inch.
Snap-O-Matic and Collins Machine Fit
The dies mount directly into compatible Snap-O-Matic die heads or Collins threading machines without adapters. This integration keeps the threading station compact and leaves the machine’s capacity free for other die sizes. No separate die stock or manual handle is required when the machine is used.
For Pipe Threading on Compatible Machines
Plumbers and pipefitters cutting NPT threads on the listed materials with a Snap-O-Matic or Collins machine will find the set matches their equipment. Workers needing left-hand threads, different thread forms, larger pipe diameters or manual die stocks should look at other tooling. The product carries a California Proposition 65 warning for cancer and reproductive harm.
