Hand Tap 3/4 inch LH G for pipes
Hand Tap 3/4 inch LH G DIN 5157/2 HSS is a specialized 2-piece set (ripper + finisher) designed for manual cutting of left-hand cylindrical G(BSP - British Standard Pipe) pipe threads with a profile angle of 55 degrees. The tool is made of high-quality HSS high-speed steel, which ensures durability, precision and resistance to wear in daily use.
The 3/4-inch G thread has an outside diameter of 26.441 mm (according to ISO 228-1). Theleft-hand (LH - Left Hand) direction of the notch is used in systems where protection against self-loosening of threaded connections is required - m.in. in hydraulic systems, gas systems or rotary mechanisms.
The 3/4 inch Left Hand Pipe Thread er is a reliable tool for assemblers, locksmiths and service technicians who expect full compliance with BSP standards and precise, safe processing of hand threads.
- 2-piece set (DIN 5157/2) - ripper and finisher for precision threading in two stages.
- G 3/4 inch left-hand thread - external thread diameter 26.441 mm (ISO 228-1).
- Thread profile of 55 degrees - BSP standard ensures full compatibility with piping systems.

Frequently asked questions
1. Why is the G 3/4 inch LH thread cutter 26.4 mm in diameter? G 3/4 inch how much is mm? And how many cm is it?
The question "G 3/4 inch how many mm" or "G 3/4 inch how many cm" often arises when selecting tools for pipe threading. Contrary to appearances, the value of 3/4 inch(that is, 26.4 mm or 2.64 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 3/4-inch threaded pipe has an outside diameter of 26.4 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.
