Value Collection 20603 Pipe Tap 1/2-14 Nps 4 Flute Hss

Product Description

The VALUE COLLECTION 20603 is a standard pipe tap designed to cut 1/2-14 NPS (National Pipe Straight) threads in ferrous and non-ferrous materials. Built from high-speed steel (HSS) with an oxide gold finish, this tap delivers consistent thread form and extended tool life in demanding shop and field applications. It features 4 flutes for efficient chip evacuation and a 1.375 inch thread length. The 0.6875 inch shank diameter and 0.515 inch square drive size are compatible with standard tap wrenches and machine holders. Plumbers, pipefitters, and machinists use this tap when threading pipe fittings, couplings, and manifold ports to NPS standards.

This tap is suited for threading straight pipe connections in plumbing, HVAC, and general mechanical applications where NPS thread form is required. It is appropriate for use in both hand-tapping operations with a tap wrench and light-duty machine tapping setups. Typical applications include threading ports in pipe fittings, valve bodies, and fluid system components. The oxide gold finish provides a basic level of corrosion resistance during storage and use.

Installation Notes

This tap should be installed and used by qualified machinists, plumbers, or pipefitters familiar with thread-cutting procedures. Always secure the workpiece and use appropriate cutting fluid to reduce heat and extend tap life. Back the tap off periodically to break chips, especially in deeper holes. Follow applicable codes such as IPC and IFGC where threaded pipe connections are part of a regulated installation.
