Die 7/8 inch G HSS – professional tool for medium-diameter pipe threads
Die 7/8 inch is a robust 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 precise threading of steel and copper pipes and brass components. Compliance with DIN EN 24231 ensures compatibility with fittings used in industrial and municipal installations.
Key advantages of the 7/8 inch pipe threading die
- HSS high-speed steel – allows machining of materials with tensile strengths up to 800 MPa while maintaining long-lasting edge sharpness
- BSPP parallel thread with a 55° profile – enables leak-tight connections with a gasket in water and pneumatic systems
- Outside diameter 30.20 mm – meets the BSP standard for the nominal size of 7/8 inch
- Manufactured in accordance with DIN EN 24231 – confirms dimensional compliance with international pipe thread standards
- Deep flutes – provide effective chip evacuation when threading medium and larger diameters
The 7/8 inch pipe threading die is an intermediate size between the popular 3/4 and 1 inch sizes, used in specialized installations requiring nonstandard flow capacity. It is used in hydraulic, pneumatic, and heating systems, as well as industrial fittings. The tool is suitable for threading steel and copper pipes and brass components.
The 7/8 inch threading die is a tool for professionals working on projects with specific diameter requirements. Order a product that combines precision with durability.
Frequently asked questions
The 7/8 inch value (22.225 mm / 2.22 cm) specifies the nominal pipe size, not the thread diameter. The BSP system was designed to account for wall thickness, so the actual outside diameter of the G 7/8 thread is 30.20 mm.
The G (BSPP) 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.
