Metal Detectable Cam-and-Groove Hose Coupling Gaskets

Form a tight seal on cam-and-groove hose connections without fear of contaminating your food processing line. The metal additive in these gaskets can be picked up by a metal detector, so you can find and remove them if they fall into your line. They are FDA compliant, meaning they are safe for direct contact with food, and they help you comply with Hazard Analysis and Critical Control Point (HACCP) programs for food safety.

EPDM—EPDM gaskets hold up better than Buna-N and silicone in water, steam, and UV light. However, they will degrade from contact with oil.

Buna-N—Buna-N gaskets are the best choice for applications with animal or vegetable oil, since they will not degrade from oil contact.

Silicone Rubber—Silicone rubber gaskets can be used with the widest range of temperatures, and are often used in high-temperature applications. They withstand steam better than Buna-N, but not as well as EPDM.
