A sanitary union is a detachable pipe connection commonly used in food, beverage, dairy, and pharmaceutical processing systems. It allows two pipes to be easily connected or disconnected for cleaning, maintenance, or inspection. Sanitary unions are designed with smooth surfaces and hygienic seals to prevent contamination and ensure safe fluid transfer. They are usually made from stainless steel grades like 304 or 316 and come in standards such as DIN, SMS, 3A, and ISO. This fitting provides a reliable, leak-free, and easy-to-install solution for sanitary pipeline systems.
