TC Clamps
What are TC Clamps?
TC Clamps, also known as Tri-Clover clamps, are quick-release sanitary fittings used to securely join two ferrule ends in a Tri-Clover assembly. Designed for high hygiene environments, these clamps provide a tight, leak-proof seal in processing lines handling food, beverages, dairy, and pharmaceuticals. Their tool-free assembly and disassembly make them a preferred choice for systems that demand frequent cleaning and maintenance.
Asiad Steel Industries is a leading supplier of premium TC Clamps, trusted by process industries for delivering durable, corrosion-resistant, and precision-engineered connections.
