CFR 21 FDA 177.2600 O-rings are designed to be used in food processing applications where there is a potential for direct or indirect contact with food. These O-rings are made from materials that have been tested and approved by the FDA for use in food contact applications. The regulation specifies the allowable materials, processing methods, and conditions of use for these O-rings.

The materials used in CFR 21 FDA 177.2600 O-rings must be non-toxic, non-carcinogenic, and non-mutagenic. They must also be resistant to chemical and thermal degradation, as well as to microbial growth. These materials include various elastomers, such as silicone, fluorocarbon, and EPDM, as well as certain plastics, such as polytetrafluoroethylene (PTFE) and polyethylene (PE).

CFR 21 FDA 177.2600 O-rings are used in a variety of food processing equipment, including pumps, mixers, valves, and filters. They are typically used to create a seal between two surfaces, preventing leaks and contamination. Some common applications of these o-rings include sealing the connections between processing equipment and piping, as well as sealing the lids on food storage containers.
