1/4 Inch NPT Thread Dimensions in MM
The 1/4 inch NPT (National Pipe Taper) thread is a common thread size used in piping and tubing systems. To ensure proper compatibility and assembly, it's essential to understand the thread dimensions in millimeters.
Thread Dimensions in MM:
The following table outlines the thread dimensions for a 1/4 inch NPT thread in millimeters:
| Dimension | Value (mm) |
|---|---|
| Major Diameter | 13.16 |
| Minor Diameter | 10.44 |
| Pitch | 1.814 |
| Threads per Inch | 18 |
| Thread Length | 6.35 |
Thread Series:
The 1/4 inch NPT thread is part of the NPT thread series, which includes a range of thread sizes from 1/16 inch to 2 inches. The NPT thread series is commonly used in North America for piping and tubing systems.
Thread Type:
The 1/4 inch NPT thread is a tapered thread, which means that the diameter of the thread decreases as you move from the major diameter to the minor diameter. This tapered design allows for a secure seal when connected to a corresponding female thread.
Applications:
The 1/4 inch NPT thread is commonly used in various industries, including:
- Plumbing: for connecting pipes and fittings in residential and commercial plumbing systems
- HVAC: for connecting heating, ventilation, and air conditioning systems
- Industrial: for connecting pipes and fittings in industrial processes and equipment
Conclusion:
Understanding the thread dimensions in millimeters is crucial for ensuring proper assembly and compatibility in piping and tubing systems. The 1/4 inch NPT thread dimensions in MM outlined above provide a reference for designers, engineers, and technicians working with NPT threads.
