Food Safe O-Rings

June 15, 2022 – by Eastern Seals

Here at Eastern Seals we provide our seals to a variety of different industries, supplying to the food industry is one of our biggest industries but it also very important it complies with the law. That is why we only use specific ingredients that have been determined by the U.S. Food and Drug Administration.

Since in this industry you are working closely with food that may be eaten by the general public there are struct standards in place for materials that come into contact with consumables.

In this post we’re going to look at some of the most popular used materials used that are safe to use in the food industry.



Silicone is one of the most popular materials to use due to its range of properties. It has great thermal stability, low chemical reactivity, low toxicity and great heat resistant properties. Not only that, because of all these great features it also allows for longer service life, meaning as a company you will save more money by not having to constantly pay for replacements.

Food grade silicone is a great material for ensuring no foreign substances will contaminate foods.


This material combines high temperature resistance with chemical resistance. It is also nearly invisible when it is under water, but it actually doesn’t absorb it. This material is commonly used in aircraft engines and seals for automotive fuel handling systems – but they also have their uses when it comes to the food industry.


This is mainly used for jobs that demand both flexibility and ruggedness. It is made from odourless and tasteless compounds so it is great to use in the food and beverage industry.


Neoprene has a great smooth finish, a good resistance to abrasion and it repels greasy food products. It was developed as a perfect oil-resistant substitute for natural rubber.

This material is the preferred choice for refrigeration seals, and can also be used in the transport sector.
