It is made for use with 500A Mono Die Heads and is built to withstand the demands of production threading in trade environments. The high-speed steel construction maintains cutting edge sharpness through repeated use, making it well-suited for plumbing and pipefitting applications where consistent, clean NPT threads are required. Licensed plumbers, pipefitters, and mechanical contractors are the primary users of this die.
This die is intended for threading 1/4-inch pipe to the NPT standard at 18 threads per inch. It fits the RIDGID 500A Mono Die Head configuration and is suited for use in residential, commercial, and light industrial plumbing installations. Right-hand thread orientation matches the standard for NPT pipe connections used throughout domestic water supply, gas distribution, and mechanical piping systems.
Designed for use with RIDGID 500A Mono Die Heads. Cuts 1/4-18 NPT right-hand threads as specified by ANSI pipe thread standards.
Pipe dies are installed and serviced by licensed plumbers and pipefitters familiar with power threading equipment. Always power down and disconnect the threading machine before changing or seating dies. Ensure the die head is clean and free of debris before installing the die to achieve proper thread form and fit. Follow the threading machine manufacturer's guidelines and applicable codes such as the IPC or IFGC for thread engagement requirements on pipe joints.
