Small cable glands with pressure compensation valve

SPP is a grommet with a pressure compensation valve, recommended for environments that require uniform pressure. The depressurizing grommet is inserted into the DES divisible frames and, thanks to its valve, compensates for the pressure in the rooms, thus preventing temperature differences and the consequent formation of condensation. The ventilation element has an M12x1 thread and can be removed to use threaded connectors and sensors.
