PUR-JZ or PUR-OZ grey polyurethane control flex

PUR-JZ or PUR-OZ grey flexible control cable has a tough polyurethane (PUR) outer sheath. Designed for connecting, measuring, checking and control applications in the machine, plant and tool making industries. The PUR sheath provides increased mechanical and chemical resistance when compared to standard PVC.

PUR-OZ = without earth, PUR-JZ = with earth (included in core count).

These durable yet flexible cables are suitable for installation indoors or outdoors, in dry, moist or wet areas including where exposed to harsh mechanical strain or dragged over sharp/rough surfaces. These cables are resistant to mineral oils, coolant emulsions and UV-radiation.
