Tightening values Tightening torque for metric cable glands

These torque values are recommended for metric SKINTOP ® cable glands in order to attain protection category IP68, 5 bar and strain relief category A according to EN 50262. Given values are tightening torques for the intermediary, as well as maximum tightening torques for the cap nuts. To prevent damage to the outer sheath, please note that different cable materials require various torques.
