NAVF series cable glands, with a female threaded outlet fitting, are suitable for use in areas with the risk of explosion, allowing the direct insertion of non-armoured cables in explosion proof enclosures, light fixtures, outlets, plugs, etc. Their structure makes them suitable for environments which are particularly difficult, such as marine environments, or where there are subjected to the mechanical stresses and impacts which often occur in heavy industry, where safety is the utmost priority. They are supplied with a sealing ring which is stretched over the cable at the inlet, ensuring ‘Ex d’ execution and an IP66/68 protection rating. The result is a cable gland which provides maximum performance, longterm reliability and safety, is compatible with a wide range of the main, commercially available cables, and complies with the most recent applicable regulations.
