Machine Tap G 1 inch blind
Machine Tap G 1 DIN 5156/35 HSSE Fra is a heavy-duty thread cutter designed for cutting G1 inch cylindrical pipe threads in through holes. Made from high-grade HSSE high-speed steel, it provides long life, wear resistance and stable operation in steel, stainless steel and cast iron.
This model has a short C-type nut (2-3 working coils), which facilitates a confident start of threading and good control of the cutting process. Made in accordance with the requirements of DIN 5156/35, it guarantees precise dimensions and reliability in industrial applications and pressure installations.
Machine Tap G1 inch is a popular choice in hydraulics, pneumatics and piping applications where tightness, repeatability and compliance with ISO 228 are key.
- HSSE steel - increased resistance to wear and heat loads
- Cap C - 2-3 working coils, ideal for through holes
- For use in steel, stainless steel and cast iron
- Precision manufacturing - conforms to DIN 5156/35 standard
- Dedicated to BSP (G) pipe connections in industrial and workshop environments
Frequently asked questions
1. Why is the G 1 inch threader 33.25 mm in diameter? G 1 inch how much is mm? And how many cm is it?
The question "G 1 inch how many mm" or "G 1 inch how many cm" often arises when selecting tools for pipe threading. Contrary to appearances, the value of 1 inch(that is, 33.25 mm or 3.32 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-inch G thread has an outside diameter of 33.25 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.
