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.
