The hydraulic straighteners of PETIG's RK series are used to straighten steel wire. These tools are mainly used when wire is cut from the coil and has to be straightened for further processing. The different models allow to straighten wire up to a diameter of 40 mm.
Especially flexible is the AS 20, PETIG's new development, which is powered by powerful lithium-ion accumulators.

Based on the HYDROCUT series, they share the same properties regarding hydraulic pump units.

The pressure units matching the diameters to be straightened have to be ordered separatedly.
