Stainless Steel Tri-Clamps

Stainless steel tri-clamps (also known as tri-clover clamps) are quick-connect sanitary fasteners engineered to securely join two flanged pipe fittings (ferrules) with a gasket between them, creating a leak-proof, hygienic seal. They are widely used in clean-room and high-purity processing applications because they completely eliminate threaded gaps where bacteria or organic material could accumulate.

• • The Clamp: The external metal collar that hinges around the assembly and uses a wing nut or bolt to tighten.
  • Two Ferrules: The matching, flanged metal pipe ends that are compressed together.
  • A Gasket: The flexible seal placed in the grooved faces between the ferrules. 

• Material Grades: Most commonly cast or forged from SUS304 Stainless Steel for standard rust resistance and durability, or SUS316/316L Stainless Steel for enhanced corrosion and chemical resistance in highly acidic environments. 
• Hinge Types:
  • • Single-Pin: The most common and convenient type for fast, daily tool-free teardowns.
    • Double-Pin / High-Pressure: Features a dual-hinge configuration that applies a more uniform squeeze across the ferrule face, allowing it to hold higher fluid pressures safely. 

• Common Sizes: Standard sanitary sizing typically ranges from 1 inch to 4 inches (often referencing the outer diameter of the tube, though the flange face itself is wider—for example, both 1-inch and 1.5-inch sizes share a 50.5mm flange outer diameter).

• Brewing & Distilling: Connecting kettle ports, fermenters, pumps, and transfer hoses.
• Food & Dairy Processing: Processing lines handling juices, milk, and soft foods safely without contamination.
• Pharmaceuticals & Chemical Processing: Maintaining sterile environments for drug manufacturing and handling corrosive chemical media
