Manufactured from carbon steel, this die delivers consistent thread form across right-hand NPT cuts used in standard piping and conduit installations. The hex body measures 1-7\/16 inches across flats, allowing it to seat properly in compatible die stocks and pipe threading machines. At 1\/2 inch thick and 0.17 pounds, the die is a compact replacement component suited for job-site and shop use by licensed plumbers, pipefitters, and electricians running threaded conduit.\u003c\/p\u003e\u003cp\u003eThis die is used wherever 1\/4-18 NPT threads are required on pipe or conduit runs in residential and commercial installations.
