SR301R Threaded Remote Seal
Brand: Smar International CorpThe SR301R is a threaded connection seal. The diaphragm is welded to the flange. This model is always supplied with housing, because the process thread is located in this part.
The (optional) flush connection in the housing enables to remove deposits on the diaphragm without disconnecting the seal.
The parts are bolted together and sealed with a gasket. This model is supplied with bolts and nuts in Stainless Steel 316.
