The use of components in potentially explosive atmospheres, such as in the chemical and pharmaceutical industries, agriculture, woodworking and the metal industry, is governed by strict standards. With its LevelEx Ex cable gland, PFLITSCH is breaking new ground in terms of safety and ease of assembly.

The LevelEx consists of just four parts, which are simple and safe to assemble and take up little space. A special feature of the gland: the sealing elements have a captive design and cannot be lost during assembly. The LevelEx is available in nickel-plated brass and stainless steel, each version in sizes M16 to M75, with NPT threads from 3/8" to 2 ½". Its large sealing range means that cables from 7 mm to 66 mm can be tightly sealed. Thanks to the silicone sealing insert, the glands can be used in applications in the temperature range from –60 °C to +130 °C. 

The compact Ex cable gland complies with protection types “Ex-db” for flameproof enclosure, “Ex-eb” for increased safety and “Ex-ta” for protection by enclosure. It satisfies the demanding requirements of protection ratings IP 66, IP 68 and Type 4X.

The international ATEX, IECEx, VDE, DNV, CCC, KCs and UL Listed certificates – the latter demanding very stringent requirements – granted verify that this PFLITSCH cable gland can be reliably used even under extreme conditions. In an industrial environment, a product can be either UL Recognized or UL Listed. The difference lies in the degree of compliance with UL requirements. In potentially explosive atmospheres, the complete set of requirements must be met.

In order to obtain ATEX and IECEx certification, the cable gland must pass an overpressure test conducted at 30 bar for 10 s, in accordance with EN 60079-1. The LevelEx was tested with a test pressure of 48.6 bar, which corresponds to a reference pressure of 32.4 bar if the gland is used at an operating temperature of –60 °C.
