G 1 HSS inch die – a versatile tool for pipe threads
1 inch die is a versatile tool designed for cutting G (BSPP) parallel pipe threads with a 55° profile. Made of high-speed steel (HSS), this inch pipe threading die combines manufacturing precision with high durability when threading steel, copper, and brass pipes. Compliance with DIN EN 24231 ensures dimensional compatibility with industrial valves and fittings and piping connectors.
Key advantages of the 1 inch die for inch threads
- HSS high-speed steel – ensures efficient machining of materials with a tensile strength of up to 800 MPa and long-lasting cutting edge sharpness
- BSPP standard with a 55° thread angle – ensures leak-tight connections with a gasket in pressurized installations
- The most popular pipe size – used in water supply, heating, pneumatic, and industrial installations
- Manufactured to DIN EN 24231 – confirms compliance with international inch pipe thread standards
- Flutes with optimized geometry – enable efficient chip evacuation and comfortable operation
The 1 inch pipe threading die is used wherever reliable threaded connections in standard diameters are needed – from residential central heating systems and compressed air systems to pipelines in production halls. The tool handles black steel and galvanized pipes as well as nonferrous metal components.
The 1 inch pipe threading die is essential equipment for an installer's workshop and maintenance teams. Order a tool that meets the standards and achieve precise threads in every installation.
Frequently asked questions
The designation 1 inch (25.4 mm / 2.54 cm) indicates the nominal pipe size, not the actual thread diameter. The G 1 inch die has an outside diameter of 33.25 mm because the BSP standard accounts for the wall thickness of pipes used in installations.
The G (BSP) thread has a parallel form with a constant diameter along its entire length. Connections of this type are not self-sealing – a flat gasket, an O-ring, or PTFE tape is required.
