SS 316 hygienic sight glass contains 2 to 3% molybdenum, an element absent in SS 304. That addition sharpens corrosion resistance against chlorides, acids, and the aggressive cleaning agents used during CIP and SIP cycles. Pharmaceutical and food-grade applications depend on this resistance to stop pitting near welds and gaskets after repeated wash cycles. STILONN Valves & Controls builds these sight glasses with PTFE-lined bodies rated for the caustic detergents common in dairy, beverage, and drug manufacturing plants. Steam sterilization above 121°C wears down SS 304 faster than SS 316. The extra durability means fewer replacements and a longer service life in harsh operating conditions.
