FDA 21 CFR 177.2600 (Food-Contact O-Rings)
FDA-compliant O-Rings under 21 CFR 177.2600, the regulation for rubber articles intended for repeated food contact.
Sealing food and beverage equipment means the O-Ring itself has to be safe for contact with what you are making. In the United States, the relevant rule for rubber seals is FDA 21 CFR 177.2600. The O-Ring Store stocks compounds formulated to meet it.
What 21 CFR 177.2600 covers
21 CFR 177.2600 is the U.S. FDA regulation titled “Rubber articles intended for repeated use.” It lists the ingredients permitted in such rubber and sets extractive limits, measured by water and n-hexane extraction tests, for material that repeatedly contacts food. A compliant compound is built only from FDA-sanctioned ingredients and passes those extraction limits.
Repeated use vs single use
The regulation applies to repeated-use articles, such as the seals and gaskets in food and beverage equipment that contact product again and again over their service life. Single-use or one-time-contact articles fall under different FDA regulations, so a part specified for repeated service is what 177.2600 is written for.
O-Ring compounds that meet it
FDA-grade O-Rings are available in several base elastomers, so you can match chemical and temperature needs while staying compliant:
- Nitrile (NBR), commonly a white 70-duro FDA grade
- EPDM FDA
- Silicone FDA
- FKM (Viton) FDA
