FAQ
Are NPT and G threads compatible?
G threads and NPT threads are not compatible due to their differences in angles, shapes, and thread pitches (threads per inch). This means that G threads cannot be used interchangeably with NPT threads. It is important to ensure that the correct type of thread is used for a particular application to ensure a proper fit and functionality. For example, if a G thread is used in a situation that requires an NPT thread, it may result in leaks or other issues. Therefore, it is essential to understand the specifications and requirements of the thread type needed for a specific application.
Can you thread NPT into G?
The G (BSP / BSPP) standard is widely used in Europe and other parts of the world. It is important to note that even though the threads may appear very similar, they are not interchangeable. On the other hand, the NPT (US Standard) thread has a tapered design with a 60-degree thread pitch. Its purpose is to create a seal by tightening the threads together, often with the help of pipe tape to address any potential minor leaks. This distinction should be kept in mind when working with different thread standards.
What is the G thread?
G threads, also known as BSPP threads (British Standard Pipe Parallel), are cylindrical pipe threads with a 55° apex angle. Originally used on inch-based pipes, these threads are measured in threads per inch. So, when you hear someone mention “G” threads, they are essentially referring to BSPP threads. In summary, BSPP and G threads are parallel straight threads that are identical in nature.
What is G thread fitting?
G Thread, also known as British Standard Pipe Parallel (BSPP), is a type of straight thread with a consistent diameter.
