Century Drill Tool 95203 3/8-18 Npt Pipe Tap 2 Pack

Product Description

The Century Drill Tool Co Inc 95203 is a 3/8-18 National Pipe Thread (NPT) tap designed for cutting internal threads in pipe fittings, couplings, and pipe ends. Threads are precision-formed to NPT specifications, ensuring consistent, accurate results on every pass. The tap is heat treated and tempered to achieve file-hard threads, extending service life under repeated use. This is a hand-cutting tap intended for manual operation with a standard tap wrench. The package includes 2 taps. Plumbers, pipefitters, HVAC technicians, and maintenance trades reach for this tool when creating or restoring NPT female threads in metal pipe and fittings.

The 95203 is suited for internal threading on all types of pipe materials where a 3/8-18 NPT thread form is required. Common applications include threading pipe fittings, couplings, valves, and manifold bodies in plumbing, HVAC, and general mechanical systems. The 3/8-18 designation means 3/8-inch nominal pipe size at 18 threads per inch, which is the standard NPT pitch for this pipe size. It is a hand-tap design, making it appropriate for bench work and field repairs where a tap handle or wrench provides the necessary torque control.

Installation Notes

This tap is intended for use with a standard tap wrench by a qualified tradesperson. Apply cutting oil to the tap and work material before starting to reduce friction and extend tap life. Advance the tap slowly with steady, even pressure, backing off periodically to break chips and clear the flutes. Follow applicable plumbing and mechanical codes for thread engagement and fitting assembly requirements.
