Diaphragm seals are suited for protecting gauges from high temperatures, corrosive liquids and fluids with the potential to clog. They also can help prevent loss of process fluid and the effects of pulsation. Interchangeable with most seal brands, according to the manufacturer, the diaphragm seals are available in stainless steel and exotic metals in online and offline designs. They include threaded, flush, flange, saddle and wedge models. High pressure ratings are available on some models. Assorted flanged models are available in ANSI flange sizes from 0.5 to 4”, Class 50 to Class 2500.
