As a standard of chemical and petroleum plants, the process gauge & diaphragm seal assembly is one of the most common types of seal assemblies. Diaphragm seals are used to isolate the gauge from media that is corrosive, high temperature, highly viscous, or tends to crystallize or polymerize.

Pressure ranges to 9000 psig and above are possible. By selecting proper components, system fill fluid, and with proper system fill fluid preparation, ARCO Engineering is even capable of supplying a highly reliable assembly for vacuum applications as shown below.
