Eagle Cutting Tool PT-12500-115-I Hss Npt Pipe Tap

Product Description

The EAGLE CUTTING TOOL PT-12500-115-I is a high-speed steel (HSS) NPT pipe tap sized for 1-1/4 inch diameter pipe at 11-1/2 threads per inch (TPI). This tap cuts standard National Pipe Taper threads into pipe fittings, couplings, and threaded port openings. It is used by plumbers, pipefitters, and mechanical contractors when threading ferrous and non-ferrous materials to NPT specifications. The HSS construction provides the hardness and wear resistance needed for clean thread formation in steel, cast iron, brass, and similar materials.

This tap is suited for maintenance, repair, and fabrication work in commercial and industrial piping systems where NPT-threaded connections are required. It is commonly used to chase damaged threads or cut new threads in pipe flanges, manifolds, valve bodies, and threaded fittings. The 1-1/4 inch by 11-1/2 TPI sizing covers a widely used pipe thread specification in plumbing and gas distribution systems.

Key Features

• High-speed steel (HSS) construction for durability and wear resistance
• Cuts NPT (National Pipe Taper) threads to standard specification
• 1-1/4 inch diameter, 11-1/2 TPI thread form
• Suitable for threading ferrous and non-ferrous pipe materials
• Import-grade tool appropriate for general service and repair applications

Compatibility

Designed as a standard NPT pipe tap for use wherever 1-1/4 inch by 11-1/2 TPI National Pipe Taper threads are required in plumbing, gas, and mechanical piping applications.

Installation Notes

Pipe taps are installed by licensed plumbers, pipefitters, and qualified tradespeople using a tap wrench or machine tapping setup. Always isolate and de-pressurize the line before threading into existing pipe or fittings. Apply cutting oil generously during the tapping process to extend tool life and produce clean threads. Follow applicable code requirements, including IPC and IFGC, for threaded connection specifications.
