# Tri Clamp System

Tri Clamp (TC) connectors offers both fast and leak-free connections. TC connectors is the preferred system in the food and beverage industry because it offers a sanitary connection which is easy to clean.

The Brewtools products uses as much of these connectors and fittings as possbile as it offers increased flexibility and is easy to use. The Pro Series brewing systems mainly use 34mm TC connectors. They have a 34mm outside diameter and you use 34mm Tri Clamps to hold two connectors together with a gasket between them. All our gaskets are food grade silicone.

We also use other sizes TC connectors. The Steam hats use a 4" TC flange on the top, and the Steam Condenser mainly uses 2" TC connectors.

Tri Clamps are normally tightened by hand.&#x20;

4", 6" and 8" might need additinal tightening by a tool if used to hold pressure like on the unitank fermenter.

Here is a list of the most frequent used TC sizes

| **Size** | **Outer diameter \[mm]** |
| -------- | ------------------------ |
| 34mm     | 34mm                     |
| 1.5"     | 50.5mm                   |
| 2"       | 64mm                     |
| 3"       | 91mm                     |
| 4"       | 119mm                    |
| 8"       | 217mm                    |

The pipe diameter can vary within each TC size. It's important to use the correct type of gasket to not restrict flow and make cleaning easier.
