Value Collection CCT1594 Npt Tap Die Set 12 Piece

Product Description

The VALUE COLLECTION CCT1594 is a 12-piece NPT tap and die set designed for cutting and chasing National Pipe Taper threads in pipe, fittings, and threaded assemblies. The set covers a range from 1/8-27 up to 1-11/2, making it suitable for the most common pipe thread sizes encountered in plumbing, HVAC, gas, and general mechanical work. Both taps and dies are manufactured from carbon steel. The hex-profile dies seat securely in a standard die stock. The full set ships in a plastic storage case that keeps pieces organized on the job or in the shop.

This set is intended for use by plumbers, pipefitters, HVAC technicians, and mechanical contractors who need to cut new NPT threads or restore damaged ones on steel pipe, black iron, and threaded fittings. It covers the six most frequently encountered NPT sizes in residential and light commercial piping systems: 1/8-27, 1/4-18, 3/8-18, 1/2-14, 3/4-14, and 1-11/2. The included taps and dies in matching sizes allow complete thread cutting or repair without sourcing individual pieces.

Installation Notes

A licensed plumber, pipefitter, or HVAC technician should perform pipe threading work on pressurized or gas-carrying systems in accordance with applicable local codes and the IFGC or IPC as adopted. Apply cutting oil to both taps and dies before and during threading to extend tool life and produce clean thread form. Back the tap or die off frequently to break the chip and clear the flutes. Always de-energize, depressurize, and isolate any system before cutting or chasing threads on installed pipe.
