Eagle Cutting Tool PT-25000-8-I Hss Npt Pipe Tap

Product Description

The EAGLE CUTTING TOOL PT-25000-8-I is a 2-1/2-inch, 8 TPI high-speed steel (HSS) NPT pipe tap designed for cutting tapered pipe threads in ferrous and non-ferrous materials. Built to National Pipe Taper (NPT) standards, this tap produces leak-resistant threaded connections in pipe fittings, valves, manifolds, and related plumbing and HVAC components. The 2-1/2-inch nominal size and 8 threads-per-inch pitch make this a large-diameter tap suited for heavy-duty piping work. HSS construction provides the toughness and wear resistance needed for production tapping and field use. Plumbers, pipefitters, and HVAC mechanics working on commercial and industrial piping systems are the primary users of this tool.

This tap is suited for threading pipe entry points in steel, iron, brass, and aluminum where NPT tapered threads are specified. Typical applications include threading ports on valve bodies, pipe unions, pump housings, and heavy-wall conduit fittings. The large 2-1/2-inch size is most common in commercial mechanical rooms, industrial process piping, and large HVAC hydronic systems where full-size pipe tapping is required. It is classified as an import-grade tool, appropriate for lower-frequency production runs or job-site use where cost-efficiency is a priority.

Key Features

• HSS construction provides durability and resistance to heat generated during tapping operations
• NPT tapered thread form produces leak-resistant pipe connections per ANSI standards
• 2-1/2-inch nominal diameter with 8 TPI pitch for large-diameter pipe threading
• Import-grade classification offers a cost-effective option for periodic or non-production use
• Compatible with standard tap wrenches and machine tapping setups sized for large-diameter taps

Compatibility

Designed for use in any application requiring a 2-1/2-8 NPT tapered pipe thread. Fits standard tap wrenches and tapping machines capable of accepting large-diameter HSS pipe taps.

Installation Notes

Pipe taps of this size are typically driven by a licensed pipefitter or plumber using a heavy-duty tap wrench or machine tapping setup. Always apply cutting fluid rated for the material being tapped to extend tap life and improve thread quality. Ensure the workpiece is securely fixtured before beginning the tapping operation to prevent tap breakage. Follow applicable code requirements such as IFGC or IPC for threaded pipe connections in gas or plumbing systems.
