Tri-clamp fittings (also known as Tri-Clover, a branded name of tri-clamp fittings) are one of the main types of sanitary fittings in use by breweries and other food processing plants. They’re easy to assemble consisting of two flanged connections with a gasket in between, secured by a clamp. They’re also extremely easy to clean as there’s no threads or crevices where nasties can grow. These fittings are the most common type of connection available with a wide variety of options at affordable prices. For all these reasons, we stock these (and use them almost exclusively in our own brewing set-up).
 
This gasket is made of silicone with a raised, beaded seal. Tri-clamp assemblies rely on gaskets to create a watertight seal – it’s important not to overtighten the clamp as this may damage the parts. Hand-tight is all that's needed for a secure, leak-proof connection - let the gasket do its job.
