Reotemp’s Threaded Flush Face Seals are ideal for high and medium pressure applications where process media clogging is a concern. The diaphragm is welded onto the end of the threads allowing for continuous flow of process media across the diaphragm and preventing any build-up of solids. Selection of process connection will greatly impact accuracy and temperature sensitivity.
