    FDA O-Rings Description:

    Ever wanted to make Viton or silicone more chemical resistant? When you order PTFE encapsulated materials you can have the best of both worlds. PTFE Encapsulated materials are ideal for when you need the versatility of Viton® but need it to be chemically inert, or if you need the high temperature properties of silicone but also need it to be more wear resistant.

    FDA O-Rings O-Rings Uses:


    Understanding what is required for an application and how to produce or where to source that item are different issues. At American Seal and Packing we have been sourcing food grade materials and distributing them (in the case of o-rings) or producing them (in the case of gaskets). When a customer advises the seals they need are for a clean room or CIP/SIP system we understand they need FDA approved products. The uses of this product are dependant on the material of the core being used and if the core is solid or hollow.


    FDA O-Rings and gaskets must be manufactured using compounds that are compatible with the human body. The United States standard is "FDA" which provides guidelines as to what can be contained in "FDA" product. In the U.S.A. two other important standards includes NSF which is directed at the water industry. The Milk and Milk products industry has their own standard of "3A" which requires o-rings to be able to be cleaned and receive bactericidal treatment including steam sanitation. Other countries have different standards to effectively produce the same results. WRAS is the standard in the United Kingdom and is a standard directed at potable water standards. Germany uses the KTW standard which is also directed towards protecting drinking water for humans.

     

    FDA grade effects on CIP systems (Clean In Place). Clean in place is an important aspect to the food industry. Piping for sausage, beer, cheese, or any other food, must be designed so as not to trap particles that can rot or become mold, which of course can make us sick. It’s critical that the Silicone, Buna, Viton or EPDM o-rings or gaskets used in the system will not promote bacterial growth.
