G 1 1/8 HSS inch die – a tool for medium-diameter pipe threads
The 1 1/8 inch die is a professional tool for cutting G (BSPP) parallel pipe threads with a 55° profile. Made of high-speed steel (HSS), this inch pipe threading die offers high precision and durability when threading steel, copper, and brass pipes. Compliance with DIN EN 24231 ensures dimensional compatibility with industrial valves and fittings and pipeline connectors.
Key features of the 1 1/8 inch die for inch threads
- High-quality HSS steel – ensures effective 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 precise threaded connections that require a gasket in pressurized systems
- Size for medium-diameter piping systems – ideal for hydraulic and pneumatic systems and industrial transmission lines
- Manufactured to DIN EN 24231 – ensures compliance with international standards for inch pipe threads
- Flutes with carefully designed geometry – ensure efficient chip evacuation and comfortable operation
The 1 1/8 inch pipe threading die is used wherever robust medium-diameter threaded connections are needed – in industrial installations, cooling systems, compressed air systems, and plant pipelines. The tool is suitable for threading black steel and galvanized pipes and nonferrous metal components.
The 1 1/8 inch pipe threading die is a solution for professionals carrying out industrial installation and service work. Choose a tool that meets the standards and achieve excellent threading results.
Frequently asked questions
The 1 1/8 inch dimension (28.575 mm / 2.86 cm) refers to the nominal pipe size, not the thread diameter. The G 1 1/8 die has an outside diameter of 37.90 mm due to the design of the BSP system, which accounts for pipe wall thickness.
No, the G (BSP) thread has a parallel form with a constant diameter along its entire length. Connections of this type require an additional seal – a flat gasket, an O-ring, or PTFE tape.
