Typical rubber o-ring and application
rubber o-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
The rubber o-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the rubber o-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
Static applications of rubber o-ring may include fluid or gas sealing applications in which:
The O-ring is compressed resulting in zero clearance.
The O-ring material is vulcanized solid such that it is impermeable to the fluid or gas.
The O-ring material is resistant to degradation by the fluid or gas.
Rubber o-ring are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable and have simple mounting requirements. They have been tested to seal up to 5000 psi (35 megapascals) of pressure.The maximum recommended pressure of an O-ring seal depends on the seal hardness and gland clearance.
Nitrile rubber (NBR, HNBR, HSN, Buna-N): a common material for o-rings because of its good mechanical properties, its resistance to lubricants and greases, and its relatively low cost and suitable for general hydraulic and pneumatic sealing system
NBR also has low resistance to ozone, weathering and aging. HNBR has considerable improvement of the resistance to heat, ozone and aging, and gives it good mechanical properties
low temperature.Standard silicones are resistant to water (to 100 °C), aliphatic engine and transmission oils and animal and plant oils and fats. Silicones are generally not resistant to fuels, aromatic mineral oils, steam (short term to 120 °C is possible), silicone oils and greases, acids or alkalis. Fluorosilicone elastomers are far more resistant to oils and fuels. The temperature range of applications is somewhat more restricted.
Good resistance to hot water and steam, detergents, caustic potash solutions, sodium hydroxide solutions, silicone oils and greases, many polar solvents and many diluted acids and chemicals. Special formulations are excellent for use with glycol-based brake fluids. Unsuitable for use with mineral oil products: lubricants, oils, or fuels. Peroxide-cured compounds are suitable for higher temperatures.[18]
FKM rubber ring shows excellent resistance to high temperature,acid-base and other chemicals, FKM withstands almost
every hydraulic oil (including phosphate oil series),
lubricating oil, gasoline and synthetic oil as well.
