TC Union
What are TC Unions?
TC Union (Tri-Clover Union) is a sanitary connection consisting of a clamp, two ferrules, and a gasket to form a leak-proof joint between pipelines. These unions are used in industries where hygienic, tool-free, and quick disconnection is necessary for line cleaning or modification. Their modular design and smooth finish prevent product contamination and ensure a high level of cleanliness.
Asiad Steel Industries supplies high-quality TC Unions engineered to meet the rigorous demands of modern process industries.
