Why Choose the Cembre FDM40 Neoprene Flat Sealing Ring?
The Cembre FDM40, manufacturer code 3017383, is a professional flat neoprene sealing ring designed for compatible M40 metric cable-entry connections. Part of Cembre's FDM range of cable-gland accessories, it provides a resilient sealing interface between compatible cable glands, fittings and electrical enclosure surfaces.
The FDM40 has an internal diameter of 38 mm, an external diameter of 46 mm and a compact 1.2 mm thickness. These dimensions make it suitable for compatible ISO M40 cable-entry assemblies where a correctly sized flat sealing ring is required between mating surfaces.
Manufactured from resilient rubber and specified as a neoprene sealing ring, the FDM40 provides a straightforward solution for professional panel building, machinery and enclosure installations. Its flat annular design allows it to be fitted neatly beneath compatible M40 cable-entry hardware.

Reliable Sealing for M40 Cable Entries
Flat sealing rings are positioned between compatible mating surfaces in cable-gland and enclosure-entry assemblies. As the components are tightened, the resilient ring is compressed between the surfaces, helping provide a consistent sealing interface while retaining the compact profile required for professional electrical installation hardware.
The Cembre FDM range provides purpose-designed sealing rings for metric cable-entry connections. The FDM40 combines M40 compatibility with a 38 mm internal diameter, 46 mm external diameter and 1.2 mm profile, making it suitable for panel builders, machine manufacturers, electrical contractors and maintenance engineers using compatible M40 cable-entry systems.
