Diaphragm Seals

WIKA

981.1x & 981.2x In-Line Diaphragm Seal

The WIKA 981.18, 981.19, 981.20 and 981.21 in-line diaphragm seals with threaded connections, due to their circular design, can be mounted directly into the pipeline, meaning no special measuring point connection is required. Through the integration into the process line, turbulences, dead spaces, corners and other obstructions can be avoided.
