Tri Clover

Tri-clover fittings — also sold as tri-clamp or TC — are the sanitary standard on unitanks, kettles and commercial gear: two flanged ferrules, a silicone seal between them, and a clamp to pull the joint tight. No thread to strip, nothing to seize, and it comes apart for cleaning in seconds.

The range covers 1.5 inch, 2 inch, 4 inch and 8 inch sizes: clamps, ferrules, beaded and flat silicone seals, blanking plates, elbows, barb and threaded adapters, thermo ports and carbonation stones. When matching sizes, measure the flange's outside diameter, not the pipe bore — a "1.5-inch" tri-clover flange is actually 50.5 mm across, and that catches everyone once.
