Die 7/8 inch left-hand G HSS – tool for larger left-hand pipe threads
Die 7/8 inch left-hand allows cutting of parallel pipe threads left-hand to the G (BSPP) standard with a 55° thread angle. Made from high-speed steel (HSS), it provides high productivity when machining larger-diameter steel and copper pipes. Compliance with DIN EN 24231 guarantees the dimensional precision required in professional gas and industrial installations.
Characteristics of the 7/8 inch left-hand die for industrial applications
- High-strength HSS steel – efficient machining of materials with tensile strengths up to 800 MPa while maintaining cutting edge durability
- Left-hand BSPP parallel thread profile with a 55° angle – designed for connections in flammable gas systems and rotating machinery systems
- Thread major diameter 30.20 mm – value compliant with the BSP standard for a nominal size of 7/8 inch
- Manufactured to DIN EN 24231 – ensures compatibility with industrial gas fittings and high-capacity pressure regulators
- Reinforced body design – designed to handle higher cutting torque on medium diameters
The 7/8 inch left-hand die is used in industrial gas systems, when installing pressure regulators on multi-liter cylinders, and in rotary machine drive systems. This left-hand size is also used in specialized acetylene and propane distribution systems in welding shops and heating plants.
Choose the 7/8 inch G HSS left-hand die for cutting left-hand threads on medium- and larger-diameter pipes. A reliable solution for industrial installers and maintenance technicians in manufacturing plants.
Frequently asked questions
The nominal value of 7/8 inch (22.225 mm / 2.2225 cm) specifies the pipe size in the BSP system, not the thread diameter. The pipe standard accounts for wall thickness, so the actual major diameter of the G 7/8 thread is 30.20 mm.
The 7/8 inch BSP left-hand thread is used in industrial gas pressure regulators, central acetylene distribution systems, and rotary machine drives. The left-hand direction prevents self-loosening under vibration and rotation.
