Basic SOR pressure switches with standard wetted parts are normally suitable for air, oil, water
and non-corrosive processes. Corrosive service and particular customer requirements may require
optional components. Refer to How to Order on page 3 to locate optional components, such as,
housing, switching elements, diaphragm systems, pressure ports and accessories. Each position in
the model number, except Accessories, must have a designator.
