Do you need seals with specialised homologations?
On more than one occasion we have commented on the importance of the choice of O-Ring seal. O-Rings are suitable for both dynamic and static applications but their success will depend on the properties of the gasket and the design of the housing.
The correct measurement, material, hardness, the temperature it will be subjected to, and the conditions in which it will be sealing. All these parameters have to be taken into account when selecting the gasket. Don’t forget that the O-Ring must comply with the special homologations that certify its suitability to come into contact with drinking water, food, beverages, medicines, fire, gas etc.
JIOrings O-Rings application is wide and varied, and is commonly used in food, health, automotive, aeronautics and oil sectors etc. but these gaskets are also present in many home appliances available at our fingertips.
Whatever the final destination, our goal is that the seals treatments always comply with health requirements, drinkability and safety required in each case by each client. That is why we have been working for years to have seals materials certified by entities and independent laboratories.
In this table you can check which mixtures comply with international homologations, and the origin of the country that issues them.
