Source O-rings, Gaskets, & Seals For Food Processing

What Are Special Seal Requirements For The Food Processing Industry?

As with O-rings, gaskets, and seals used in any industry, those designed for the food processing industry must meet the demands for reliable components made to spec, and be capable of providing the sealing capacity you need. In addition, since the equipment is used to handle and process food, beverages, meat, dairy products, pharmaceuticals, and other consumables, rubber products must meet FDA standards as food grade.

Ensuring Food Safety

The FDA has special requirements for the material used in equipment components used for all aspects of processing and packaging.

  • DA CFR 21.177.2600 paragraphs A to D covers "rubber articles intended for repeated use" and lists ingredients that can be used in rubber compounds, as well as the percentage of ingredients, for products used throughout the food manufacturing, preparation, and transportation process.
  • FDA CFR 21.177.2600 paragraphs E and F list specifications for FDA approved rubber seals that will come into contact with extractable aqueous or fatty foods, this regulation also specifies extraction test limits and requires documentation in the form of a manufacturer's FDA certificate to assure compliance

Types Of Elastomers Used In Food Processing

The FDA approves the use of rubber polymers that are resistant to the buildup of bacteria, resistant to chemicals, are flexible, odorless, and tasteless, and that perform well under a large array of working temperatures. The materials include:

  • FDA Silicone Rubber functions at temperatures ranging from -67°F to 450°F FDA and is used for numerous food service applications.
  • Nitrile (Buna-N) Rubber withstands temperatures of -40°F to 212°F and is known for its high resistance to animal fat and vegetable oils. It can handle suction and discharge for food and dairy products.
  • FDA EPDM Rubber handles a temperature range of -40°F to 250°F in applications that demand both flexibility and ruggedness. Made from odorless and tasteless compounds and usable in applications involving a transfer of oily substances, the products are used in food and beverage, dairy, and other applications.
  • FDA Neoprene® Rubber performs at temperatures ranging from -30°F to 220°F and is intended for repeated food exposure as it has excellent oil resistance. Is frequently used for food processing and industrial applications

Where Are FDA Approved Gaskets And Seals Used In Food Processing?

Within the industry, FDA approved elastomers are used in many types of equipment that use parts, such as:

  • Food Grade Gaskets & Seals
  • FDA Compliant Gaskets & Seals
  • FDA Dust Covers
  • FDA Suction Cups
  • FDA Rubber Shields
  • FDA Flexible Rubber Couplings
  • High Purity Gaskets & Seals
  • Sanitary Gaskets & Seals
