Die 1 inch left-hand G HSS – a tool for left-hand BSP pipe threads
The 1 inch left-hand die is a tool designed for cutting left-hand G (BSPP) parallel pipe threads with a 55° profile. Made of high-speed steel (HSS), this left-hand inch pipe threading die provides high accuracy when working with steel, copper, and brass pipes. The product meets DIN EN 24231 requirements, ensuring dimensional compatibility with fittings intended for systems with left-hand threads.
Features of the 1 inch left-hand die for pipe connections
- HSS construction – ensures effective machining of steel and nonferrous metals with tensile strengths up to 800 MPa
- Left-hand BSPP 55° profile – designed for connections protected against loosening during equipment operation
- Actual thread diameter 33.25 mm – conforms to the BSP standard for the nominal size of 1 inches
- Compliance with DIN EN 24231 – ensures compatibility with inch-size fittings and connectors
- Optimized flute geometry – facilitates chip removal and reduces resistance during threading
The 1 inch left-hand die is suitable wherever a standard right-hand thread would loosen on its own — on gas cylinder regulators, in rotary drives, and in specialized piping systems. The tool works well with carbon steel, copper, and brass alloy pipes.
Choose the 1 inch left-hand G HSS die when your project requires a nonstandard thread direction. Ensure reliable connections under demanding operating conditions.
Frequently asked questions
The dimension 1 inches (25.4 mm / 2.54 cm) defines the nominal pipe size within the BSP system. The actual outside diameter of the G 1 inch thread is 33.25 mm because the standard accounts for pipe wall thickness.
Using a left-hand thread in flammable gas systems protects against accidental connection to the wrong system. The left-hand direction also prevents the connection from loosening due to vibration and pressure changes.
