Value Collection 315-2140 Round Adjustable Pipe Die Npt

Product Description

The VALUE COLLECTION 315-2140 is a round adjustable pipe die used to cut 1 to 11-1/2 NPT external threads on pipe and pipe fittings. Manufactured from high-speed steel, it delivers consistent thread form and resists wear during repeated use. The adjustable design allows the operator to fine-tune the cutting diameter for a clean, accurate thread on the first pass or take a cleanup cut on previously threaded material. At 2.5 inches outside diameter, this die fits standard round die stocks and threading handles designed for that size. Plumbers, pipefitters, and maintenance trades use this die when fabricating or repairing threaded pipe connections in the field or shop.

This die is suited for threading schedule-standard pipe to 1 to 11-1/2 NPT specifications in residential and light commercial plumbing, fire protection, and mechanical piping applications. It cuts right-hand threads, which is the standard direction for NPT pipe connections. The adjustable feature makes it practical for production threading as well as one-off repair work where exact thread fit matters.

Installation Notes

This die is installed and operated by plumbers, pipefitters, or machinists using a compatible round die stock or threading machine collet. Secure the workpiece in a pipe vise before threading to prevent movement. Apply cutting oil generously during the threading operation to lubricate the cutting edges, reduce heat buildup, and improve thread finish. Follow applicable plumbing codes such as the IPC or IFGC when threading pipe for gas or water service installations.
