Die R 1/8 inch HSS – a tool for self-sealing taper pipe threads
The R 1/8 inch die is used for cutting external BSPT taper pipe threads with a 55° thread angle. The 1:16 thread taper makes the connection self-sealing without the need for flat gaskets. High-speed steel (HSS) construction ensures durability when machining steel and copper pipes, while compliance with DIN-EN 24230 confirms the dimensional precision required in pressure systems.
Features of the R 1/8 inch taper threading die for pressure connections
- High-hardness HSS steel – allows machining of materials with tensile strengths up to 800 MPa while maintaining edge sharpness
- BSPT taper thread profile with a 55° angle – self-sealing thread thanks to its 1:16 taper, ideal for hydraulic and pneumatic connections
- Thread major diameter 9.73 mm – initial value compliant with the BSP standard for a nominal size of 1/8 inch
- Manufactured to DIN-EN 24230 – ensures compatibility with pressure fittings and tapered connectors
- Precise taper geometry – ensures a leak-tight connection at the correct tightening torque
The R 1/8 inch die is used in hydraulic, pneumatic, and gas systems where leak-tight pressure connections are required. This smallest taper thread size is used in precision control systems, instrumentation fittings, and pressure gauge and pressure sensor connectors.
Choose the R 1/8 inch HSS taper threading die for cutting self-sealing pipe threads on small-diameter tubing. An essential tool for pneumatic and hydraulic system installers.
Frequently asked questions
The R (BSPT) thread has a 1:16 taper, which means the diameter changes along the thread, producing a self-sealing effect. The G (BSPP) thread is parallel and requires an additional gasket. Both have a 55° profile and an initial diameter of 9.73 mm.
The R thread is self-sealing thanks to its taper, but PTFE Teflon tape or sealing compound is recommended to improve leak-tightness. This provides a lasting leak-tight seal in pressure systems.
