Buna-N (Nitrile) O-rings that are FDA and NSF compliant are made from a high-quality synthetic rubber copolymer of acrylonitrile (ACN) and butadiene, designed to meet strict standards for use in food, beverage, pharmaceutical, and other regulated industries. These O-rings are known for their excellent resistance to oils, fuels, and many chemicals, while being safe for contact with consumables, making them ideal for applications that require compliance with both FDA and NSF standards.

Buna-N FDA & NSF Compliant O-Rings Recommended Uses

Food and beverage processing, pharmaceutical applications, medical devices, water treatment, dairy processing, and other applications requiring strict hygiene standards and chemical resistance.

Buna-N FDA & NSF Compliant O-Rings Not Recommended

Ozone, UV exposure, phosphate esters, chlorinated hydrocarbons, aromatic hydrocarbons, ketones, strong acids, and atmospheric aging.

Buna-N FDA & NSF Compliant O-Rings Limitations
  • Not suitable for exposure to ozone, UV light, or extreme weather conditions.
  • Limited resistance to high-temperature environments.
  • Not ideal for applications requiring resistance to strong acids, alkalis, or ketones.
  • Not recommended for applications that require low compression set.
