Metal Detectable Gaskets for Cam-and-Groove Hose Couplings
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 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 gaskets are the best choice for applications with animal or vegetable oil, since they will not degrade from oil contact.
Silicone 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.

Oil-Resistant Buna-N Gaskets for Grip-Lock Hose Couplings
These gaskets are made of oil-resistant Buna-N.
Use the 0.86” OD gasket on double grip-lock hose couplings, which are also known as Thor couplings. They're compatible with Dixon Dual-Lock series, National-A series, and Perfecting P-series hose couplings.
Use the 1.072” OD gasket on grip-lock hose couplings, which are also called Bowes couplings. They're compatible with Dixon Dix-Lock series and Perfecting N-series hose couplings.
