Value Collection MSC-04662094 Pipe Tap 1-11/2 Npt Hss

Product Description

The VALUE COLLECTION MSC-04662094 is a standard NPT pipe tap designed for cutting internal tapered pipe threads in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap handles threading tasks in ferrous and non-ferrous materials across plumbing, HVAC, and industrial piping applications. The 1-11/2 NPT thread size pairs with a 1-3/4-inch thread length and five flutes, providing balanced chip evacuation and consistent thread form. It is a standard tool for machinists, pipefitters, and plumbers who need reliable NPT thread cutting without specialty coatings.

This pipe tap is suited for threading 1-inch NPT connections in pipe flanges, fittings, valves, and manifolds found in residential and commercial plumbing, gas distribution, and HVAC piping systems. The regular hook geometry makes it appropriate for use in standard drill press and hand-tapping operations on mild steel, cast iron, brass, and similar workpieces where NPT thread engagement is required.

Key Features

• 1-11/2 NPT thread standard for tapered pipe thread cutting
• Five flutes for efficient chip removal and consistent thread form
• High-speed steel construction for durability across common metals
• Bright, uncoated finish suitable for use with standard cutting fluids
• 1-3/4 inch thread length accommodates full NPT engagement depth
• Regular hook geometry compatible with hand and machine tapping operations

Compatibility

Designed for cutting 1-11/2 NPT internal tapered pipe threads; suitable for use in standard tapping applications on pipe fittings, flanges, and threaded ports requiring NPT thread form.

Installation Notes

This tap is installed by a machinist or pipefitter using a tap wrench, drill press, or tapping machine. Always apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before tapping and back off periodically to break chips. Inspect tap flutes for damage or clogging before each use to avoid thread damage or tap breakage.
