Chemical Seal Gauges

These are used to prevent aggresive or contaminating medium from entering the internals of a conventional pressure gauge, widely used in the petrol chemical industries.  They have a larger bore than a standard pressure gauge which also prevents clogging.

Available in a selection of thread sizes and wetted parts.  This can be determined by the process media and pressure range.  Please contact us and we can advise you on the appropriate seal to suit your application.
