The Definition of G1/2 Connector

A G1/2 connector, also known as a G thread or a British Standard Pipe Parallel (BSPP) connector, is a type of threaded connection commonly used in plumbing and industrial applications. It is named after its size, with the “G” indicating the nominal pipe size and the “1/2” indicating the diameter and thread pitch.

The G1/2 connector follows a parallel thread design, which means that the threads are straight and do not taper. This allows for a secure and leak-proof connection when tightened properly. The connector’s dimensions are standardized, ensuring compatibility with other components and fittings that use the same thread size.

One of the key features of the G1/2 connector is its versatility. It can be used for a wide range of fluid and gas applications, including water pipes, gas pipes, hydraulic systems, and pneumatic systems. The connector is suitable for both high-pressure and low-pressure applications, making it a popular choice in various industries.

Additionally, the G1/2 connector is often made from durable materials such as brass, stainless steel, or plastic, depending on the specific application requirements. This provides strength and resistance to corrosion, ensuring the longevity and reliability of the connection.

It is important to note that the G1/2 connector is a parallel thread and should not be confused with other thread types such as the NPT (National Pipe Thread) or the BSP (British Standard Pipe) taper threads. Using the wrong type of connector can result in improper sealing, leaks, and potential damage to the system.
