Product Description
Description
O-rings are 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 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.
Advantages
Compact design
Easy assembly
Economic solution
Symmetry that reduces the risks of an assembly error

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 has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.

FKM (fluorinated rubber)
Depending on their structure and fluorine content, fluoroelastomers can vary in terms of chemical resistance and resistance to cold. This FKM-based rubber is very often used for high-temperature hydraulic and pneumatic systems, industrial valves, injection/fuel systems, motor seals and high-vacuum systems.

FVMQ (fluorosilicone rubber)
The FVMQ has mechanical and physical properties that are very similar to those of VMQ. However, the FVMQ offers better resistance to fuels and mineral oils. However, resistance to hot air is not as good as that of VMQ.
Chemical resistanceAromatic mineral oils (IRM 903 oil)

Aromatic hydrocarbons with a low molecular weight (benzene, toluene)
Temperature range-70°C / +175°C
 
ACM (Polyacrylate)
Polymers containing ethyl acrylate (or butyl acrylate) have a small amount of monomer, which is necessary for cross-linking; ACM is a material with better heat resistance than NBR. It is often used for automatic gearboxes.

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.
