R25 Coupling Sleeves

A coupling sleeve serves as a crucial link in connecting drill rods and shank adapters, facilitating seamless assembly in various construction applications such as open pit mining, underground mining, roadway excavation, anchoring engineering, blast furnace taphole, tunnel engineering, hydropower projects, quarrying, and other construction endeavors.

Distinguished by its internal threaded sleeve, this component comes in two primary structures: the full bridge coupling sleeve and the reducing coupling sleeve. The full bridge coupling sleeve is particularly advantageous for open-air construction. It boasts easy disassembly, a stable connection, and minimal risk of getting stuck during operations.

On the other hand, the reducing coupling sleeve features different threads at its ends, enabling the connection of compatible products under specific conditions, adding versatility to its applications. Thread sizes available include R32, R38, T38, T45, and T51, catering to diverse requirements in the construction industry.
