FDA O-Ring – Food-Grade Silicone O-Rings for Safe & Compliant Sealing
Introduction
When sealing components come into contact with food, drinking water, or medical products, safety is not optional. That's where FDA O-Rings come in.
At Xiamen Jinshun Sealing Technology Co., Ltd., we manufacture custom FDA-compliant silicone O-rings designed for food, beverage, medical, and sanitary applications. Our FDA O-rings are engineered to meet CFR 21.177.2600 requirements, ensuring they are safe, traceable, and suitable for repeated contact with food and sensitive media.
Whether you are sourcing for OEM equipment, ODM projects, or global distribution, our FDA O-rings deliver consistent sealing performance while meeting strict regulatory expectations.

What Is an FDA O-Ring?
An FDA O-ring is a sealing component made from materials that comply with U.S. Food and Drug Administration (FDA) regulations for food and medical contact.
It is important to clarify a common misunderstanding:
The FDA does not "certify" O-rings.
Instead, manufacturers like us certify that our O-rings are FDA-compliant by using approved raw materials and controlled manufacturing processes.
What Does FDA-Compliant Mean for O-Rings?
FDA compliance is governed by CFR 21.177.2600, which defines rubber materials allowed for repeated contact with:
- Dry foods
- Aqueous foods
- Fatty foods
FDA Extraction Limits (Key Data)
| Food Type | Test Medium | Maximum Allowable Extraction |
|---|---|---|
| Dry Food | As manufactured | Meets formulation & curing rules |
| Liquid Food | Distilled water | ≤ 20 mg / sq. inch |
| Fatty Food | n-Hexane | ≤ 175 mg / sq. inch |
Our FDA silicone O-rings are formulated and tested to meet these limits under good manufacturing practices (GMP).
