Inch die G 1/8 HSS – compact tool for small-diameter pipe threads
Die 1/8 inch is a precision tool designed to cut G (BSPP) parallel pipe threads with a 55° thread angle. Made of high-speed steel (HSS), this inch pipe threading die ensures accuracy and durability when threading small steel, copper, and brass components. Compliance with DIN 24231 ensures dimensional compatibility with pneumatic fittings and connectors used in precision control systems.
Key features of the 1/8 inch die for inch threads
- HSS high-speed steel – allows machining of materials with tensile strengths up to 800 MPa while maintaining long-lasting edge sharpness
- BSPP standard with a 55° thread angle – enables leak-tight connections with a gasket in low- and medium-pressure systems
- Popular size in pneumatic and automation applications – standard size for pressure gauges, control valves, and pressure sensors
- Manufactured to DIN 24231 – confirms compliance with international inch pipe thread standards
- Flutes with precise geometry – ensure clean chip evacuation when threading small diameters
The 1/8 inch pipe threading die is used in applications requiring small threaded connections – industrial pneumatic systems, automation systems, measuring equipment, and centralized lubrication systems. It is also a common size in hydraulic systems in machinery and equipment. The tool works with thin steel and copper tubing and brass components.
The 1/8 inch pipe threading die is an indispensable tool for automation technicians and industrial equipment service technicians. Invest in precision and cut threads that meet the highest standards.
Frequently asked questions
The 1/8 inch dimension (3.175 mm / 0.32 cm) specifies the nominal pipe size, not the actual thread diameter. The G 1/8 die has an outside diameter of 9.73 mm because the BSP standard is designed to account for pipe wall thickness.
Regardless of size, the G (BSP) thread has a parallel design with a uniform diameter along its entire length. These connections do not seal on their own – a flat gasket, O-ring, or Teflon tape is essential.
