Cle-line C65571 Hex Pipe Die 1/8-27 Npt Carbon Steel

Product Description

The CLE-LINE C65571 is a hex pipe die designed to cut external NPT threads on pipe and fittings. Built from carbon steel, it produces right-hand 1/8-27 NPT threads and fits into standard hex pipe die stocks that accept a 1-1/16 inch hex body. At 3/8 inch thick, it is sized for the smaller pipe diameters common in plumbing, gas line, and instrumentation work. Plumbers, pipefitters, and mechanical contractors reach for this die when threading small-diameter pipe on the bench or in the field with a manual or powered threading handle.

This die is suited for threading 1/8-inch nominal pipe in residential and light commercial plumbing, HVAC refrigerant line accessories, pneumatic control tubing, and instrumentation connections where NPT is the specified thread form. It produces the tapered thread geometry required for pressure-tight, leak-resistant joints when assembled with pipe thread sealant or tape per standard trade practice.

Key Features

• Cuts 1/8-27 NPT right-hand external threads for standard pipe fittings
• Carbon steel construction provides durability for repeated threading operations
• 1-1/16 inch hex body fits compatible hex pipe die stocks
• 3/8 inch thickness suits compact die stocks used on small pipe sizes
• Right-hand thread direction matches standard NPT pipe and fitting convention

Compatibility

Designed as an OEM-style replacement or service die for hex pipe die stocks that accept a 1-1/16 inch hex die body and are rated for 1/8-inch nominal pipe threading.

Installation Notes

Installation of this die is performed by licensed plumbers, pipefitters, or qualified mechanical technicians. Seat the die securely in the die stock before threading; a loose die will produce off-pitch or damaged threads. Apply cutting oil liberally to the workpiece during threading to extend die life and produce clean thread form. Inspect finished threads with a NPT ring gauge or test fitting before pressurizing the line.
