TC Ferrule
What are TC Ferrules?
A TC Ferrule (Tri-Clamp Ferrule) is a crucial connection component in sanitary piping systems, providing a smooth, secure interface between pipes and fittings. These ferrules are welded onto process lines or vessels and allow for quick, clamp-based assembly using gaskets and tri-clamp connectors. Used extensively in food processing, beverage, dairy, biotech, and pharmaceutical industries.
Asiad Steel Industries is a trusted supplier of premium-quality TC Ferrules in various sizes, surface finishes, and stainless steel grades.
