Overview

The Irwin Hanson 8203 is a 1/4-18 NPT taper tap measuring 2.6 inches and weighing 0.12 pounds, used to cut standard tapered pipe threads. It fits anyone threading pipe fittings built to the 1/4-18 NPT standard.

NPT taper taps cut a tapered thread that matches standard pipe fitting hardware, so this tool is sized for one specific fitting standard rather than general purpose threading. Irwin Hanson is a recognized name in taps and dies, and the compact 2.6 inch length with a light 0.12 pound weight fits a hand held single point tool.

Who it's for

Suits anyone cutting or cleaning up 1/4-18 NPT pipe threads, such as plumbing or fluid fitting work. Not useful for a different thread size or a straight, non tapered thread.

Pros and cons

Pros
  • Matches the 1/4-18 NPT pipe thread standard
  • Irwin Hanson brand
  • Compact and light for hand use
Cons
  • Limited to one specific thread size
  • Tap only, no die included

Performance notes

A taper tap cuts thread depth gradually along its length, which helps start a clean thread in a fitting before reaching full depth. At 2.6 inches and 0.12 pounds it is sized for hand tapping with a standard tap wrench rather than machine use.
