Inch threader G1/2 inch for stainless steel and cast iron
Machine Tap G 1/2 DIN 5156 C HSSE Narex is a precision tapping tool designed for making G1/2 inch cylindrical pipe threads in through holes. Made of high-grade HSSE high speed steel with cobalt additive, it provides high durability, wear resistance and reliable operation when machining steel, stainless steel and cast iron.
The tapping tool has a C-type nut (2-3 working coils), which makes it possible to start threading quickly and accurately. It meets the requirements of DIN 5156, which guarantees dimensional compliance and high quality workmanship, essential for industrial and piping applications.
Machine Tap G1/2 inch is one of the most widely used models in pneumatics, hydraulics, compressed air systems and industrial systems where tightness and standardization of the connection is crucial.
- High-quality HSSE steel - increased resistance to wear and heat loads
- Cap C - 2-3 working coils, ideal for through holes
- Application - for steel, stainless steel and cast iron
- Conforms to DIN 5156 - dimensional repeatability and high precision
- Dedicated to BSP pipe connections in industrial environments
Frequently asked questions
1. Why is the G1/2 inch threader 20.96 mm in diameter? G 1/2 inch how much is mm? And how many cm is it?
The question "G 1/2 inch how many mm" or "G 1/2 inch how many cm" often arises when selecting pipe threading tools. Contrary to appearances, the value of 1/2 inch(that is, 20.96 mm or 2.09 cm) does not mean the diameter of the thread, but the nominal size of the pipe to which the thread fits. In practice, a 1/2 inch G thread has an outside diameter of 20.96 mm, because G (BSP) pipe threads are designed for pipes with thick walls.
For 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.
