| Actual Diameter (Inches) |
National Pipe Thread (NPT) (Fractional) |
| 0.405″ | 1/8″ |
| 0.540″ | 1/4″ |
| 0.675″ | 3/8″ |
| 0.840″ | 1/2″ |
*NOTE: A very common misconception is that a 1/4″ NPT measures as 1/4 inch on a ruler or tape measurer. However, that is not the case. NPT will measure larger in diameter. Above is a sizing reference to help clarify.
