Irwin Hanson 5104 Round Adjustable Pipe Die 3/8-18 Npt

Product Description

The IRWIN HANSON 5104 is a round adjustable pipe die designed to cut external 3/8-18 NPT threads on pipe and fittings. The die features a 1.5-inch outside diameter and is machined from carbon steel for durability in production and field threading applications. The adjustable design allows the operator to fine-tune thread fit and take multiple passes for a cleaner cut. This die is a standard tool for plumbers, pipefitters, and mechanical contractors who thread pipe on the job or at a shop bench.

The 5104 is suited for threading 3/8-inch nominal pipe to the NPT standard, which is the tapered thread specification used throughout North American plumbing, gas piping, and industrial piping systems. It is appropriate for both residential and light commercial work where field-cut NPT threads are required on steel or iron pipe. The right-hand thread direction matches the standard for the vast majority of pipe connections encountered in the trade.

Key Features

• Adjustable die body allows thread depth fine-tuning and multi-pass cutting for accurate NPT thread form
• 3/8-18 NPT thread specification for standard North American pipe threading
• 1.5-inch outside diameter fits compatible round die stocks
• Carbon steel construction provides strength for repeated threading cycles
• Right-hand thread direction matches standard pipe assembly requirements

Compatibility

Designed as a replacement or supplemental round pipe die for use in 1.5-inch round die stocks that accept standard 3/8-18 NPT pipe dies.

Installation Notes

Installation of this die requires a compatible round die stock sized for a 1.5-inch OD die. Secure the die firmly in the stock before threading. Apply cutting oil generously during the threading operation to extend die life and improve thread quality. Follow applicable codes such as IFGC or IPC when threading pipe for gas or plumbing service, and inspect each cut thread before assembly.
