Hand Tap G 3/8 inch left for pipes
Hand Tap 3/8 inch left G DIN 5157/2 HSS is a specialized two-piece set (ripper + finisher) designed for manual cutting of cylindrical G(BSP - British Standard Pipe) pipe threads with left-hand direction of cut. The tool is made of high-quality HSS high-speed steel, which guarantees high durability, wear resistance and precise thread guidance.
The 3/8-inch G-type thread has an outside diameter of 16.662 mm (according to ISO 228-1) and a thread profile of 55 degrees. The left-hand direction of the notch is used m.in. in hydraulic, pneumatic and gas systems, where the thread must counteract the self-loosening of connections.
The left-hand G 3/8 inch pipe threader is an excellent choice for precision service and production tasks in both industrial installations and locksmith work.
- A 2-piece set (DIN 5157/2), the peeler and finisher provide progressive, controlled threading.
- Left-hand thread G 3/8 inch - external thread diameter 16.662 mm.
- 55 degree profile - conforms to the BSP pipe thread standard.
- HSS high speed steel - wear resistant, ideal for steel, non-ferrous metals and plastics.
- For hand-held applications - in gas, hydraulic and industrial installations.

Frequently asked questions
1. Why hand Tap G 3/8 inch left is 16.66 mm in diameter? G 3/8 inch how much is mm? And how many cm is it?
The question "G 3/8 inch how many mm" or "G 3/8 inch how many cm" often arises when selecting pipe threading tools. Contrary to appearances, the value of 3/8 inch (that is, 16.66 mm or 1.66 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 3/8-inch threaded pipe has an outside diameter of 16.66 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.
