190mm Length
Coupling sleeve
Coupling sleeves, other name is Coupling, when using rock drills with male shank adapters and a conventional drifter rod, a coupling is required to join the adapter to the rod, ensuring the ends touch for efficient energy transmission. Couplings are also used to connect several rods to each other in the same way. Couplings have a middle stop to prevent over-threading on to the drill rod.
Coupling are important accessories for tubing and casing pipes.
couplings are used to connect two joints of tubing or coupling
accessories together. Couplings are short length of heavy well pipe
with the same threads on each end. Threaded coupling sleeves are
made of high quality of alloy steels and CNC machining guarantee
our reliable and consistent quality control of coupling
sleeves.Both semi-bridge and full-bridge coupling sleeves are
manufactured by us in different sizes as below:
Thread sizes: R22, R25, R28, R32, R35, R38, T38, T45, T51.
We can manufactures semi-bridge, full bridge coupling sleeves for the percussive tools.
Semi-Bridge Coupling sleeve
- Small non-threaded bridge in the center
- Steel cannot thread past bridge area
- Smaller diameter steel end portions fit together in the centre bridge area of the coupling
- Semi-bridged couplings are most suited to high torque machines
- Most rope and T threaded couplings are semi-bridged
