The WIKA 990.49 diaphragm seal is designed to be screwed into a threaded flange. Due to the extended diaphragm, the diaphragm seal can be used at thick-walled or insulated locations in pipeline and vessel construction.

Assembly of the diaphragm seal to the measuring instrument may be made via a direct connection, for high temperatures via a cooling element or via a flexible capillary.

For the material selection, WIKA offers a variety of solutions, in which the upper body of the diaphragm seal, the extended diaphragm and the wetted parts can be made of identical or different materials. The diaphragm and the extended diaphragm can, as an alternative, be coated.
