Value Collection MSC-04662078 Pipe Tap 3/4-14 Npt Hss

Product Description

The VALUE COLLECTION MSC-04662078 is a standard NPT pipe tap designed to cut internal tapered pipe threads in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap produces 3/4-14 NPT threads — a common pipe thread standard used throughout plumbing, HVAC, and industrial piping systems. The 5-flute design provides clean chip evacuation and stable cutting geometry in typical ferrous and non-ferrous materials. With a thread length of 1.375 inches and a shank diameter of 0.9063 inches, this tap suits both hand tapping and machine tapping operations. Plumbers, pipefitters, and HVAC technicians rely on NPT taps like this when threading new ports, repairing stripped fittings, or fabricating custom pipe connections in the field or shop.

This tap is suited for threading 3/4-inch pipe fittings, valves, couplings, and manifold ports to NPT specifications in residential and commercial applications. Typical uses include threading ports in pipe flanges, mechanical equipment housings, and fluid system components where a pressure-rated tapered thread seal is required. The regular hook geometry makes it appropriate for general-purpose tapping in a wide range of materials including mild steel, cast iron, aluminum, and brass.

Key Features

• 3/4-14 NPT thread form for standard tapered pipe thread applications
• High-speed steel construction for durability across a broad range of workpiece materials
• 5-flute design promotes chip clearance and consistent thread form
• Bright, uncoated finish suitable for general-purpose tapping with standard cutting fluids
• Thread length of 1.375 inches accommodates typical pipe wall thicknesses
• Regular hook geometry compatible with hand tapping and most machine tapping setups

Compatibility

Designed as a general-purpose replacement or shop-stock NPT pipe tap for use wherever 3/4-14 NPT internal threads are required in ferrous and non-ferrous metal workpieces.

Installation Notes

NPT pipe taps are installed by licensed plumbers, pipefitters, and HVAC technicians using a tap wrench or machine tapping fixture. Always apply an appropriate cutting fluid to extend tap life and improve thread quality. Start the tap square to the workpiece to avoid misaligned or torn threads. Follow ANSI and applicable trade code requirements for thread engagement depth and pressure ratings when threading fittings in pressurized systems.
