Tri-Clover Clamps (Tri-Clamp / Sanitary Clamp)
Tri-Clover Clamps are used to securely connect two ferrules with a gasket placed between them, creating a hygienic and leak-resistant joint. They are widely used in sanitary pipework, processing equipment, tanks, valves, and pumps where regular cleaning, inspection, and maintenance are required.
We supply Tri-Clover Clamps according to customer requirements. Clamps can be supplied as a complete set with ferrules and gaskets, or each component can be supplied separately if required.
Standard Tri-Clover Connection Components
A standard Tri-Clover connection normally includes three components:
| Component | Image | Description |
|---|---|---|
| Clamp |  |
Fits over the ferrule flanges and compresses the gasket to secure the connection. |
| Ferrules |  |
Flanged ends welded or threaded onto tubes, pipes, valves, or fittings. |
| Gasket |  |
Sits between the two ferrule faces to create a hygienic seal. |
Material Options
Tri-Clover Clamps and ferrules are available in the following stainless-steel grades:
| Material | Typical Application |
|---|---|
| SS304 | General food, beverage, dairy, and sanitary applications |
| SS316 / SS316L | Applications requiring higher corrosion resistance, including chemical, pharmaceutical, and more demanding environments |
Gasket Options
Gaskets are available in different materials to suit the product, temperature, and cleaning chemicals used in the application.
| Gasket Material | Typical Application |
|---|---|
| EPDM – Black | Steam, hot water, CIP systems, and general sanitary applications |
| Silicone | Food, beverage, dairy, and applications requiring flexibility over a wide temperature range |
| PTFE | Chemical-resistant and high-purity applications |
