These Buna-N rubber O-rings comply with Paragraph 177.2600 of Title 21, sub-paragraphs a) through d), Code of Federal Regulations, "Rubber Articles Intended for Repeated Use". It should be noted that the Food and Drug Administration does not actually approve any rubber compounds. Rather it publishes a list of permissible ingredients and the maximum allowable concentration of each. FDA (Food Grade) rubber products are commonly used in applications where food or consumables are present, such as in the food processing, beverage, dairy, meat packing, and pharmaceutical industries. FDA rubber products are also found within most food packaging equipment, such as gable-top packaging machinery.
