These O Rings are made (among others) from very varied chemical synthetic rubber: NBR, EPDM, HNBR, FKM, VMQ, ACM, AEM, as well as Polyurethane, PTFE, FKM-FEP or VMQ-FEP, which provides a large selection of materials that are chemically compatible with a wide range of products and fluids. The dimensions of the housing are defined by the O'Ring cross-section Ød2. These O-Ring are extremely easy to use, both for static and dynamic applications, and do not require any maintenance or adjustment. They can be used under pressure and at significant speeds and temperatures by selecting the right quality and by carefully following the installation instructions. The O-Rings are a simple, efficient and economic solution. 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.
EPDM (Ethylene Propylene Diene Monomer rubber)
As an Ethylene Propylene Diene Monomer copolymer, EPDM is commonly used for hot water taps, cooling systems, brake systems, dishwashers and washing machines.
HNBR (Hydrogenated Nitrile Butadiene Rubber)
This HNBR-based elastomer is obtained through selective hydrogenation of the NBR's butadiene groups. It is commonly used for power-assisted steering and for air conditioning.
VMQ (silicone rubber: methyl vinyl polysiloxane)
This FVMQ-based rubber is very often used for fuel 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.
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.
AEM (ethylene acrylate rubber)
As a methyl acrylate and ethylene copolymer, AEM is considered to be better resistant to heat than ACM. Its characteristics make it an intermediary between ACM and FKM.
CR (Polychloroprene)
This CR-based elastomer is used in the refrigeration industry and for ventilation systems. This chloroprene was the first synthetic rubber to be developed and marketed.
FFKM (perfluorinated rubber)
FFKM has the best resistance to high temperatures and an excellent chemical inertia. 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.
The table below gives an overview of the physical, chemical and mechanical characteristics for each of the materials.

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.
O ring standard:The o ring sizes are specified by the inside diameter and the cross section diameter. Morgan Rubber O ring seals are manufactured according to metric and imperial international standards such as GB3452.1-92, AS 568B, DIN ISO 3601 and JIS standard. Morgan seals also accept custom sizes of almost any dimension, such as metric o rings, miniature O-rings, special O-rings with large dimensions and continuously moulded and spliced.
