G 1 3/8 HSS inch die – a robust tool for medium- and large-diameter pipe threads
The 1 3/8 inch die is a reliable tool for cutting G (BSPP) parallel pipe threads with a 55° profile. This inch pipe threading die made of high-speed steel (HSS) ensures high 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 features of the 1 3/8 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° thread profile – enables leak-tight connections with a gasket in pressurized systems
- Diameter for medium- and larger-diameter piping systems – suitable for hydraulic systems, ventilation systems, and industrial process lines
- DIN EN 24231 standard – confirms dimensional compliance with international standards for inch pipe threads
- Optimized flutes – ensure smooth chip removal and stable tool operation
The 1 3/8 inch pipe threading die is used wherever durable threaded connections of medium and larger diameters are required – in manufacturing plant installations, compressed air systems, cooling systems, and process pipelines. The tool works exceptionally well with black steel and galvanized pipes as well as nonferrous metal alloys.
The 1 3/8 inch pipe die is designed for professionals in industry and installation work. Choose a standards-compliant tool and complete threading projects with the highest precision.
Frequently asked questions
The 1 3/8 inch designation (34.925 mm / 3.49 cm) refers to the nominal pipe size, not the actual thread diameter. The G 1 3/8 die has an outside diameter of 44.32 mm because the BSP standard takes industrial pipe wall thickness into account.
The G (BSP) thread has a parallel form with a constant diameter along its entire length. Connections of this type require additional sealing – a flat gasket, an O-ring, or Teflon tape.
