For professionals in food, beverage, pharmaceutical, or biotech processing, this Megairon sanitary sight glass is a crucial visual inspection tool. It's designed for ultra-clean (sanitary) piping systems. This specific model has a 4-inch Tri-Clamp ferrule connection (fits a 115mm OD ferrule) for a 102mm OD flow pipe. The entire body is constructed from high-quality Stainless Steel 316, known for its corrosion resistance. The viewing window is made of real glass, sealed with a silicon gasket, providing a full 360-degree view of your fluid flow, bubbles, color, or particle presence. It's rated for pressures up to 120 PSI and temperatures up to 300°F. This clamp-type design makes installation and cleaning a breeze – just unclamp it for maintenance. It's perfect for high-purity applications where you need to monitor process conditions without interrupting the flow or breaking sterility. A must-have component for any sanitary process line where visual confirmation is key. It's a brand new, premium quality part that meets industry standards.
