Value Collection JY4350070 Pipe Tap 3/4-14 Npt

Product Description

The VALUE COLLECTION JY4350070 is a standard pipe tap designed to cut internal NPT (National Pipe Taper) threads in metal workpieces. It produces a 3/4-14 thread — meaning a 3/4-inch nominal pipe size at 14 threads per inch — for use in plumbing, HVAC, and mechanical piping assemblies where tapered pipe thread joints are required. The tap is made from carbon steel and features a bright, uncoated finish. With 5 flutes, it provides clean chip evacuation during tapping operations. The thread length measures 1-3/8 inches, and the shank diameter is 0.9063 inches. This tool is suited for use by plumbers, pipefitters, HVAC technicians, and machinists working in shop or field environments.

This pipe tap is used when threading pipe fittings, valves, manifolds, or equipment housings to accept 3/4-inch NPT male fittings. It is applicable in residential and light commercial plumbing, hydronic heating systems, refrigerant piping accessories, and general mechanical work where NPT-threaded connections are specified. The regular hook geometry makes it compatible with standard tapping operations in hand tapping or low-speed machine tapping setups.

Key Features

• 3/4-14 NPT thread profile for tapered pipe thread applications
• 5-flute design supports efficient chip removal during cutting
• 1-3/8 inch thread length provides adequate engagement depth for standard pipe tap operations
• Carbon steel construction suitable for tapping soft to medium-hardness metals
• Bright, uncoated finish — no coating to chip or flake during use
• Shank diameter of 0.9063 inches fits standard tap wrenches and machine tool holders for this size range

Compatibility

Designed for use in any application requiring a 3/4-14 NPT internal thread. Suitable for hand tapping or low-speed machine tapping in materials compatible with carbon steel tooling.

Installation Notes

Pipe taps are typically used by licensed plumbers, pipefitters, and HVAC mechanics. Before tapping, drill the correct tap drill size for the NPT thread and ensure the workpiece is securely clamped. Apply cutting fluid throughout the operation to extend tool life and improve thread quality. Follow applicable plumbing and mechanical codes — such as the IPC or IFGC — for thread engagement and joint requirements.
