Description
Our double-pin clamps are durable, high-quality clamps used to securely connect tri-clamp ends.
Double pin clamps are sanitary, 304 stainless steel clamps engineered for high‑purity connections in the pharmaceutical, food & beverage, brewing, and industrial sectors. Designed to join two tri‑clamp ends, they create a firm, leak‑free seal when used with a tri‑clamp gasket.
Featuring a double‑pin hinged design and cross‑hole wing nut, this product offers enhanced clearance and torque compared to single‑pin versions, making installation and removal easier in confined spaces.
Double pin clamps are sometimes called double pin tri-clover clamps, double hinge sanitary clamps, or dual-pin tri-clamps.
Pressure rating based on tightening wing nut to 25 in. lb. of torque.

304 vs. 316L Stainless Steel
304 and 316L stainless steels appear visually identical, but have distinct performance characteristics.
304 stainless steel contains approximately 18% chromium and 8% nickel, making it suitable for kitchen applications and indoor environments. It performs well under normal conditions but becomes vulnerable to corrosion when exposed to salt or harsh chemicals. This makes it the more economical option for standard uses where corrosion resistance is not a primary concern.
316L stainless steel contains 2-3% molybdenum in addition to chromium and nickel, providing superior corrosion resistance, especially against saltwater and chemicals. Furthermore, 316L has a lower carbon content than 316, increasing corrosion resistance and making it ideal for welding. While it commands a higher price point than 304, it is recommended for outdoor marine environments and food processing applications involving salt.
304 is useful for some standard applications, but for the highest level of durability and harsh environments or saltwater exposure, the additional investment in 316L stainless steel is justified for long-term success.
