Dairy Tee
What are Dairy Tees?
Dairy Tees are hygienic pipe fittings used in sanitary fluid transport systems to split or merge flow at 90-degree angles. Made from stainless steel grades such as SS 304 and SS 316L, these tees are widely used in dairy, beverage, food processing, and pharmaceutical industries where cleanliness and contamination-free flow are essential.
Asiad Steel Industries is a trusted manufacturer, supplier, and exporter of high-quality dairy tees that comply with SMS, DIN, and 3A sanitary standards.
