TC Reducer
What are TC Reducers?
A TC Reducer (Tri-Clamp Reducer) is a sanitary fitting designed to connect two pipes of different diameters in hygienic process systems. It ensures a smooth transition between varying pipe sizes without compromising the cleanliness or flow integrity. TC reducers use tri-clamp connections for easy assembly, disassembly, and cleaning, making them ideal for industries requiring strict hygiene standards.
They are widely used in food processing, dairy, beverage, pharmaceutical, and biotech applications where sanitary conditions and reliable flow control are critical.
