Flange seals

GSD rubber steel seal – flange seals with steel reinforcement

The DDL rubber steel flange seals are designed to be installed between two flanges. Prefabricated steel rings are placed into the injection/vulcanizing molds for the rubber flange seals when they are produced. The steel inlays provide the seals with excellent form stability and make the installation a lot easier. For the elastomer parts we use EPDM rubber* and NBR rubber**.
The flat seals with steel inlay correspond to the DIN flange sizes and are available in different pressure levels.
