Coupling Sleeve
Coupling Sleeve is a sleeve-shaped rock drilling component with internal threads for connecting shank adapter and drill rod, or drill rod and drill rod. We produce and provide three types of drill rod couplings– semi bridge couplings, full bridge couplings, and crossover couplings, which can meet the requirements of all applications.

Standard coupling sleeve
Standard coupling sleeve t38, also known as semi bridge coupling sleeve, has a section of the bridge without a thread in the middle. The threaded part of the drill pipe cannot be screwed through the bridge part of the coupling, and the end of the thread can closely adhere to the casing bridge zone. Standard threaded rod coupling sleeveis particularly suitable for high-torque drilling rigs. Most rope thread (R thread) and trapezoidal thread (T thread) coupling sleeves are with half-bridge type. The half-bridge type is by far the most widely used couplings.
Full bridge coupling sleeve
Full bridge coupling sleeve can completely eliminate the looseness of the coupling sleeves along with the threaded connection. It is mainly used in surface mining, with better disassembly characteristics, firmer connections, and almost no clamping situation.
Crossover couplings
Crossover couplings are used to convert different thread types or thread diameter sizes.
