What Makes O-ring Food-Grade?

The most essential aspect to determine whether it may be called FDA grade or “food grade O-ring”, is the material used in fabrication. Food grade O-rings must fulfill the FDA’s minimal material composition standard.

Food grade seals are governed to quantitative parameters for initial manufacture. They should be composed entirely of FDA-approved natural and synthetic substances. There are significant restrictions on their use with extractable goods and with watery or fatty foods. YOSON manufacture O-rings in compliance to FDA 21 CFR 177.2600 certification.

Food Grade O-Ring Materials

Several materials for O-rings exceed the guideline of the FDA for use in food applications. Below are some of the materials commonly-requested such as:

  • EPDM – Ethylene propylene diene monomer O-rings are made to resist a broad array of temperatures, lipids and phosphate esters.
  • Silicone – extremely stable material. One of the most extensive operating temperature ranges currently available. When cross-contamination is a concern, this is an excellent substance to use.
  • Nitrile Rubber – Offers high impact resistance and maintains flexibility across an extensive range of temperatures. Even after numerous daily cycles, nitrile rubber is noted for its resilience.
