R25 R28 R32 R38 Coupling Sleeve

Coupling sleeve can adopts a special structural design to reduce the energy loss during the drilling process, thus ensuring maximum impact energy at the drill bit position.

T38 T45 T51 Coupling Sleeve

Coupling sleeve includes semi bridge couplings, full bridge couplings, and crossover couplings. Different thread at the ends to connect matchable products under specific conditions.
