Irwin Hanson 5105 Adjustable Pipe Die 1/2-14 Npt

Product Description

The IRWIN HANSON 5105 is a round adjustable pipe die designed to cut 1/2-14 NPT external threads on pipe stock. Made from carbon steel, it fits a 1-1/2 inch OD die stock and cuts right-hand threads to NPT standard. The adjustable design allows the technician to dial in thread fit and make minor corrections for worn or oversized stock. Plumbers, pipefitters, and mechanical contractors use this die for field and shop threading of iron or steel pipe. It is a standard tool for any threading operation on 1/2-inch nominal pipe size work.

This die is suited for residential and commercial plumbing, gas piping, and mechanical systems where NPT-threaded connections are required. It is commonly used when cutting threads on black iron pipe, galvanized pipe, or similar ferrous pipe materials. The 1/2-14 NPT designation means the die cuts 14 threads per inch on 1/2-inch nominal pipe, the standard pitch for that pipe size. Installers working on natural gas lines, steam systems, or water distribution piping will find this die a standard fit for their threading equipment.

Installation Notes

Threading operations should be performed by a qualified plumber or pipefitter following applicable code requirements, including IFGC and IPC where relevant. Secure pipe firmly in a pipe vise before threading and apply cutting oil generously throughout the operation to extend die life and improve thread quality. Inspect the finished thread with a NPT thread gauge or a fitting check before installation. Always follow local code requirements for thread engagement length and joint compound or tape application on the completed connection.
