1/4 NPT Diameter in MM: A Comprehensive Guide
What is 1/4 NPT?
1/4 NPT (National Pipe Taper) is a type of pipe thread commonly used in plumbing and piping systems. The "1/4" in 1/4 NPT refers to the nominal pipe size, which is equivalent to 1/4 of an inch. However, the actual diameter of a 1/4 NPT pipe is slightly larger than 1/4 inch due to the tapered thread design.
Diameter of 1/4 NPT in MM
The diameter of a 1/4 NPT pipe in millimeters is approximately 13.16 mm. This measurement is based on the major diameter of the thread, which is the largest diameter of the thread.
Dimensions of 1/4 NPT Pipe
| Dimension | Measurement (in) | Measurement (mm) |
|---|---|---|
| Major Diameter | 0.525 | 13.16 |
| Minor Diameter | 0.45 | 11.43 |
| Pitch | 0.113 | 2.87 |
Understanding Pipe Thread Measurements
When working with pipes and fittings, it's essential to understand the different measurements involved. Here are some key terms to know:
- Major Diameter: The largest diameter of the thread.
- Minor Diameter: The smallest diameter of the thread.
- Pitch: The distance between threads.
Conclusion
In conclusion, the diameter of a 1/4 NPT pipe in millimeters is approximately 13.16 mm. Understanding the dimensions and measurements of pipe threads is crucial when working with piping systems to ensure proper connections and fittings.
