The dimensions for a 3 8 NPT (National Pipe Thread) refer to the size of the threaded portion of a pipe fitting. This particular NPT is commonly used in the plumbing and hydraulic industries, and the dimensions for a 3 8 NPT are as follows:
- Thread pitch: 18 threads per inch
- Major diameter: 0.656 inches
- Minor diameter: 0.562 inches
- Pitch diameter: 0.622 inches
- Thread length: 0.506 inches
These dimensions are important to know when selecting and assembling pipe fittings, as they ensure a proper and secure fit between two threaded components. Using incorrect or incompatible fittings can lead to leaking and potentially dangerous situations.
