Viking Micromatic® Standard Response Stainless Steel Sprinklers are small, corrosion-resistant, thermosensitive, glass-bulb spray sprinklers. The design consists of a solid stainless steel frame and deflector, combined with a nominal 5 mm glass-bulb operating element and a specially plated spring. These sprinklers can withstand many harsh corrosive environments that may cause regular brass sprinklers to deteriorate.  Refer to technical data sheet for required design and installation criteria.
