Century Drill Tool 97204 1/2-14 Npt Pipe Tap

Product Description

The Century Drill Tool Co Inc 97204 is a 1/2-14 National Pipe Thread (NPT) tap designed for cutting internal threads in pipe fittings, couplings, and threaded ports. Precision-formed cutting flutes produce consistent, accurate threads to NPT specification. The tool is heat treated and tempered to file-hard hardness, which extends cutting life and reduces wear during repeated use. Packaged in a quantity of 2, the 97204 is suited for hand-tapping applications where power tapping equipment is not used. Plumbers, pipefitters, and HVAC technicians reach for this tap when chasing or cutting fresh 1/2-14 NPT internal threads in the field or shop.

The 97204 is used wherever a 1/2-14 NPT internal thread must be cut or restored. Typical applications include threading pipe nipple ports, valve bodies, fittings, and manifold bosses in plumbing, HVAC, gas, and light industrial systems. The 1/2-14 thread designation refers to a 1/2-inch nominal pipe size with 14 threads per inch, the standard taper thread pitch for that pipe size. This tap is intended for hand cutting, making it practical for service calls and jobsite repairs where a tap wrench is the primary drive tool.

Key Features

• 1/2-14 NPT thread profile for standard half-inch nominal pipe internal threading
• Precision-cut flutes for consistent, accurate thread form on each use
• Heat treated and tempered to file-hard finish for extended tool life
• Designed for hand-tapping applications with a standard tap wrench

Compatibility

Designed for cutting 1/2-14 NPT internal threads in all pipe types and fitting materials compatible with hand tapping, including malleable iron, brass, steel, and similar metals commonly used in plumbing, HVAC, and gas piping systems.

Installation Notes

NPT taps are installed and driven by a qualified plumber, pipefitter, or HVAC technician using a standard tap wrench sized for the tap shank. The pipe or fitting must be securely clamped or fixtured before tapping begins. Apply cutting fluid appropriate for the base material to reduce heat buildup and extend tap life. Follow applicable codes such as IFGC or IPC when threading gas or water pipe components, and verify thread engagement and seal with approved thread sealant or PTFE tape after tapping.
