G 1 1/4 HSS inch die – a precision tool for pipe threads
The 1 1/4 inch die is a high-quality tool for cutting G (BSPP) parallel pipe threads with a 55° profile. This inch pipe threading die made of high-speed steel (HSS) ensures accuracy and repeatability when threading steel, copper, and brass pipes. Manufacture in accordance with DIN EN 24231 ensures full compatibility with valves, fittings, and connectors used in industrial installations.
Main advantages of the 1 1/4 inch die for inch threads
- HSS high-speed steel – enables threading of materials with a tensile strength of up to 800 MPa while maintaining cutting edge durability
- BSPP standard 55° profile – allows leak-tight connections with a gasket in pressurized systems
- Diameter for medium-diameter piping systems – suitable for heating, water supply, and air conditioning systems
- DIN EN 24231 standard – confirms compliance with international requirements for inch pipe threads
- Design with flutes – ensures efficient chip removal and smooth tool operation
The 1 1/4 inch pipe threading die is used in installations requiring medium-diameter threaded connections – from central heating and compressed air systems to pipelines in manufacturing plants. The tool handles black steel and galvanized pipes as well as copper alloys.
The 1 1/4 inch pipe threading die is an option for installation professionals and industrial service teams. Invest in a tool that meets the standards and produce threads of the highest quality.
Frequently asked questions
The 1 1/4 inch dimension (31.75 mm / 3.175 cm) specifies the nominal pipe size, not the actual thread diameter. The G 1 1/4 die has an outside diameter of 41.91 mm because the BSP system accounts for pipe wall thickness.
The G (BSP) thread has a parallel form with a uniform diameter along its entire length. Connections of this type are not self-sealing – a flat gasket, an O-ring, or a similar component is required.
