Frequently asked questions
1. Why is hand Tap G 7/8 inch 30.3 mm in diameter? G 7/8 inch how much is mm? And how many cm is it?
The question "G 7/8 inch how many mm" or "G 7/8 inch how many cm" often arises when selecting tools for pipe threading. Contrary to appearances, the value 7/8 inch (that is, 22.2 mm or 2.22 cm) does not mean the diameter of the thread, but the nominal size of the pipe to which the thread fits. In practice, a G 7/8 inch thread has an outside diameter of 22.2 mm, because G (BSP) pipe threads are designed for pipes with thick wallsFor this reason, always check the thread diameter value in the technical data, and do not convert inches directly to millimeters. In the BSP system, the thread size is a result of the design of the entire installation, not just the nominal dimension.
2. Is the G thread a tapered thread and does it provide tightness?
No. G thread (BSP) is a cylindrical pipe thread, which means that its diameter is constant along its entire length. Unlike tapered threads (designated as R or BSPT), G thread connections are not self-sealing. This means that a G thread does not provide a seal by itself - it requires an additional sealing element, such as a flat gasket, O-ring or plastic washer. Such a sealing method is commonly used in hydraulic, pneumatic and industrial installations.Product accessories
