Value Collection 315-2152 Adjustable Pipe Die Npt Hss

Product Description

The VALUE COLLECTION 315-2152 is a round adjustable pipe die designed to cut 1-1/2 inch - 11-1/2 TPI NPT external threads on pipe and fittings. Manufactured from high-speed steel (HSS), it delivers the hardness and wear resistance required for threading steel, iron, and similar materials in demanding trade environments. The 3-inch outside diameter round form fits standard die stocks and pipe threading machines that accept this OD size. The adjustable design allows minor size correction to achieve proper thread fit and extend die service life. Plumbers, pipefitters, and mechanical contractors rely on this die for field and shop threading operations.

This die is suited for residential and commercial plumbing, mechanical piping, and industrial pipe fabrication where NPT-threaded connections are required. It handles 1-1/2 inch nominal pipe size with an 11-1/2 threads-per-inch NPT profile, which is the standard taper thread used throughout North American plumbing and gas piping systems. The right-hand thread direction covers the vast majority of standard pipe threading applications. It is a practical choice for pipe threading work on iron, steel, and similar ferrous pipe stock.

Key Features

• High-speed steel construction for hardness and extended cutting life on ferrous pipe
• Adjustable design allows thread size fine-tuning and die longevity
• 3 inch outside diameter round form fits standard die stocks accepting this OD
• 1-1/2 inch - 11-1/2 TPI NPT thread profile for standard North American pipe connections
• Right-hand thread direction for conventional pipe threading applications

Compatibility

Designed for use in round die stocks and pipe threading machines that accept a 3 inch outside diameter round pipe die cutting 1-1/2 - 11-1/2 NPT threads.

Installation Notes

Pipe threading dies are installed and operated by licensed plumbers, pipefitters, and mechanical contractors using appropriate pipe threading machines or die stocks. Ensure the die stock or threading machine is rated for the die OD and thread size before use. Apply cutting oil generously during threading to cool the die and clear chips. Follow applicable codes including IFGC and IPC for threaded pipe joint requirements on gas and plumbing systems.
