Description
O ring seal is circular sealing elements with circular cross-sections, may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. O-ring(Viton O ring, PTFE O ring...) selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, durometer, size and cost. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.
HNBR/NBR/Viton/EPDM/Silicone Rubber O Ring Seal



Applications
O-Rings are used in a variety of fields: they are either used as sealing elements or as energizing elements for hydraulic slipper seals and wipers. Thus, the O-Ring is basically used in every field of industry including aerospace, automotive or general engineering. Today, O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, and reliable and have simple mounting.

Materials
Morgan O-rings Material Includes Nitrile rubber, fluorine rubber, ethylene propylene rubber, neoprene, chloroprene rubber, silicone rubber and so on.
NBR (Nitrile Butadiene Rubber)
Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR o ring  has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.

Chemical compatibility
A "Chemical compatibility guide" catalogue can be downloaded from the Literature section. You can also use our online "Chemical compatibility" tool free of charge.
These two tools enable you to measure the behaviour of our materials that come into contact with the majority of existing fluids. The data displayed is the result of rigorous testing at the ambient temperature and takes previous publications into consideration. Test results are not fully representative because of the specific features of your application. The tests performed actually do not consider additives and impurities that may exist under actual conditions of use, nor the potential elevation of temperatures. Other parameters can also alter the behaviour of our materials, such as the hardness, persistence, abrasion, etc. We therefore recommend performing your own tests to verify the compatibility of our materials depending on your specific application. Our technical team can provide you with any additional information.
