Diaphragm seals 1/2" threaded connection (mod. SM12)

Diaphragm seals 1/2" threaded connection are designed to isolate the sensing element of pressure gauges and pressure switches from process fluids that may be corrosive, viscous, sedimentous and/or with a high temperature. The diaphragm is welded to the body, to ensure separation of the filling fluid from the process medium. The threaded connection make it easy to use on all applications where the reduced size of the system is important and also where gauges of 2.5” (63 mm) diameter are required.
