These heads have a black epoxy electrocoat that provides good corrosion- and chemicalresistance; however, it does not provide UV protection for outdoor applications. These heads include a standard graphite material gasket that provides good chemical stability, superior creep resistance and a maximum temperature rating of 825 ºF. Pyromation 340 series terminal blocks or 400 series transmitters and DIN Form B blocks or transmitters can be mounted in these heads.
