Eagle Cutting Tool PT-1250-27-I Hss Npt Pipe Tap 1/8-27

Product Description

The EAGLE CUTTING TOOL PT-1250-27-I is a high-speed steel (HSS) NPT pipe tap sized 1/8-27, designed to cut internal tapered pipe threads conforming to National Pipe Taper (NPT) standards. This tap produces the 1/8-inch nominal pipe size thread at 27 threads per inch, creating the leak-resistant tapered engagement required for threaded pipe fittings in plumbing, HVAC, and piping systems. It is a hand and machine tap suitable for use in ferrous and non-ferrous materials. Plumbers, pipefitters, HVAC technicians, and maintenance mechanics are the primary users of this tool.

This pipe tap is used when threading new ports, repairing damaged internal pipe threads, or modifying manifolds, valves, and fittings that require a standard 1/8-27 NPT connection. It applies in residential and light commercial plumbing, hydronic heating systems, refrigeration piping, and general industrial maintenance where NPT-threaded ports are common. The 1/8-27 size is one of the most frequently encountered NPT dimensions in small-bore piping and fitting assemblies.

Key Features

• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• 1/8-27 NPT thread form for leak-resistant tapered pipe thread engagement
• Conforms to National Pipe Taper (NPT) thread standards
• Suitable for hand tapping and machine tapping applications
• Import-grade tool offering a cost-effective option for general maintenance use

Compatibility

Designed as an OEM-style replacement and standard tooling option for cutting 1/8-27 NPT internal pipe threads in pipe fittings, valves, manifolds, and ported components across plumbing, HVAC, and piping applications.

Installation Notes

Use with a calibrated tap handle or tapping machine appropriate for the tap shank size. Apply cutting fluid throughout the tapping operation to extend tool life and produce a clean thread form. Secure the workpiece firmly before beginning and back the tap out periodically to clear chips. Follow applicable trade codes such as IPC or IFGC when threading fittings used in gas or potable water service.
