Coupling sleeves are critical components in top hammer drill strings. We offer three types: Full Bridge, Semi-Bridge, and Cross-over Adapter/Coupling, ensuring seamless and efficient drilling operations.

Full-Bridge Coupling Sleeves

• Prevents the coupling from creeping along threaded joints, ensuring stability.
• Ideal for surface applications, offering excellent durability.
• Provides superior uncoupling characteristics and maintains tighter joints for enhanced performance.
• Reduced risk of jamming for smoother operations.
• Perfectly suited for machines with independent rotation, optimizing efficiency.
