Threaded, conical and crimp couplers: differences and how to choose

Cylindrical threaded (series B / A)

The thread is rolled onto the bar by machine and doesn't weaken the section. A universal equal-strength joint. Subtypes: standard, transition, positional, R/L, anchor, with lock nut. More →

Conical threaded (series LX-C)

The conical thread self-centers and assembles faster — fewer turns. The same tasks as cylindrical, but with faster installation on high-volume cage joints. More →

Crimp (LX-Press)

Cold crimping by hydraulic press on site, with no thread cutting. Suitable for smooth, dirty and cut bars where threading isn't possible. More →

How to choose

• Need versatility and documents — cylindrical threaded.
• Assembly speed matters — conical.
• Can't cut a thread / the rebar is “dirty” — crimp.
• Different diameter, fixed bars, anchorage — the matching subtype in each family.
