Eagle Cutting Tool NHD-12500-115-I Npt Pipe Hex Die 1-1/4 in

Product Description

The EAGLE CUTTING TOOL NHD-12500-115-I is a carbon steel NPT pipe hex die designed to cut external tapered pipe threads to the National Pipe Taper standard. Sized for 1-1/4 inch pipe at 11-1/2 threads per inch, this die produces the tapered thread form required for pressure-tight pipe connections in plumbing, HVAC, and industrial piping work. The hex body allows use with a standard pipe die stock. Licensed plumbers, pipefitters, and HVAC technicians reach for this die when threading carbon steel or malleable iron pipe in the field or shop.

This die is suited for threading 1-1/4 inch nominal pipe in residential and commercial applications where NPT-standard tapered connections are required. Typical use cases include gas line fabrication, steam and water piping assemblies, and mechanical room rough-in work. The imperial designation confirms thread dimensions are cut to inch-based NPT specifications.

Compatibility

Designed for use with standard hex pipe die stocks that accept 1-1/4 inch NPT dies. Intended for threading carbon steel pipe to NPT tapered thread specifications.

Installation Notes

This die is installed and operated by licensed plumbers, pipefitters, or HVAC technicians using a compatible pipe die stock. Secure the workpiece in a pipe vise before threading and apply cutting oil throughout the threading operation to extend die life and produce clean thread form. Inspect finished threads with an NPT ring gauge when thread quality is critical. Follow applicable code requirements — IPC and IFGC reference NPT thread standards for pipe joints in plumbing and gas piping systems.
