1/4 NPT to MM: A Comprehensive Guide
What is NPT?
NPT stands for National Pipe Taper, a standard for tapered threads used in pipes and fittings. It is commonly used in North America for pipes, valves, and fittings. NPT is defined by the American National Standards Institute (ANSI) and is widely used in various industries, including plumbing, hydraulic, and pneumatic systems.
What is 1/4 NPT?
1/4 NPT refers to a specific size of pipe thread, where 1/4 represents the nominal pipe size. The NPT threads have a taper of 3/4 inch per foot, which means that the diameter of the thread decreases by 3/4 inch for every foot of length.
Converting 1/4 NPT to MM
To convert 1/4 NPT to millimeters, we need to consider the outer diameter (OD) of the pipe thread. The OD of a 1/4 NPT pipe thread is approximately 13.16 mm.
Here's a rough estimate of the conversion:
- 1/4 NPT = 13.16 mm OD
Thread Dimensions
Here are the thread dimensions for 1/4 NPT:
- Major diameter: 12.7 mm
- Minor diameter: 11.4 mm
- Pitch: 1.85 mm
- Threads per inch: 18
Application and Uses
1/4 NPT is commonly used in various industries, including:
- Hydraulic systems: 1/4 NPT is used in hydraulic systems for connections, hoses, and fittings.
- Pneumatic systems: 1/4 NPT is used in pneumatic systems for connections, hoses, and fittings.
- Plumbing: 1/4 NPT is used in plumbing for connections, pipes, and fittings.
Conclusion
In conclusion, 1/4 NPT is a specific size of pipe thread with a nominal diameter of 13.16 mm. Understanding the conversion from NPT to MM is essential in various industries, including hydraulic, pneumatic, and plumbing systems. By knowing the thread dimensions and applications, technicians and engineers can ensure safe and reliable connections in their systems.
