The standard actuator cable glands provide an IP68 tightness (see topic in this FAQ) but to guarantee this tightness, they must be used under specific conditions.
They are composed of the following parts:
The dust cap DO NOT GUARANTEE an IP68 tightness. To be IP68, the cable glands must be crossed by electric cables (from 7 to 12mm). If a cable gland is not used, it must be replaced by an ISO M20 IP68 cap. To correctly tight the cable gland, the gland nut must carry out a 360° rotation after the contact between the packing elastomer and the cable.
