Rubber O Rings Seal Description
O-ring is a gasket consisting of a circular, ring-shaped piece of material. Like other gaskets, it’s used to create a seal. When two parts are joined together, they may be fitted with an O-ring to prevent pressurized liquids or gases from leaking.
To create an effective seal, though, O-rings must be constructed of specific materials. O-rings can’t be made of just any material. If a material is weak or even too rigid, it may fail to withstand the compressive forces of pressurized liquids or gases.
Specification of Rubber O Rings Seal
1. Sealing with a wide range of pressures, temperatures and tolerances
2. Easy to use
3. Standard dimensions and groove dimensions
4. Compact and lightweight
5. Long life
6. Distortion possible over a wide range and compensates for tolerances
7. Cheap
O Rings Seal Materials
In order to accommodate a large variety of applications, manufacturers make O-rings and seals using various elastomers with different physical and chemical properties. Let’s look at some of them below :
| Materials | ||
| NR | Natural Rubber | High tensile strength, good ductility |
| SBR | Styrene Butadiene Rubber | Uniform quality , less foreign matter but weak mechanical strength , can be mixed with NR , widely used in tire industry , shoe soles , tape , conveyor belt , etc |
| BR | Polybutadiene | |
| IIR | Butyl Rubber | Gas is less permeable and resistant to heat, sunlight and ozone |
| EPDM | Ethylene propylene Rubber | |
| CR | Polychloroprene Neoprene | Excellent heat aging, weather resistance, ozone resistance |
| XNBR | Carboxylated NBR / Carboxyl Butadience Acylonitrile | This gelatinization is rapid sulfur addition, short scorching time, short safe storage period, compared with the general NBR, excellent wear resistance, other characteristics are similar. |
| NBR | Nitrile Rubber ( Buna ) | Resistant to alcohol, it is the most common rubber raw material for oil seal and O-ring at present |
| HNBR | Hydrogenated Nitrile / Highly Saturated Nitrile ( HSN ) | Better temperature and weather resistance than NBR, similar oil resistance to NBR, used as seals for new R-134A refrigerant system. |
| PU | Polyurethane Rubber | High hardness, high elasticity, abrasion resistance are difficult compared to other rubbers, aging resistance, ozone resistance, oil resistance is also quite good, the general PU air tightness is good |
| CSM | Hypalon , Polyethylene | Good heat resistance, weather resistance, ozone resistance, acid resistance, often used for oxidation resistant drugs (except nitric acid, sulfuric acid) |
| ACM ( PA ) | Polyacrylate Rubber | It has good resistance to petrochemical oil, high temperature and weather. It is worse than general oil adhesive. It is widely used in automotive transmission system and power system seals. |
| ECO | Epichlorohydrin / Hydrin | Good oil resistance, heat resistance and ozone resistance |
| VAMAC | Vamac ( Ethylene / Acryllic ) AEM | Petrochemical oil resistance, heat resistance, weather resistance, ozone resistance are good, compared with PA has better temperature, widely used in automotive transmission system and power system seals. |
| SIL | Silicone Rubber | Tensile strength is worse than general rubber and does not have oil resistance, heat resistance, weather resistance, ozone resistance, low temperature are excellent, suitable for high and low temperature environment, and alcohol resistance. |
| FSIL | Fluorinated Silicone Rubber | Good resistance to oil, solvent and fuel oil, good resistance to high and low temperature, used in space parts, but mostly limited to static seals, its strength and wear resistance are not good. |
| FPM / FKM | Fluoro Carbon Rubber | High TEMPERATURE RESISTANCE IS BETTER THAN SIL, CHEMICAL resistance, MOST oil AND several solvents (EXCEPT KETones, LIPids), weather resistance, ozone resistance are good, cold resistance is poor, widely used in automobile, chemical plant parts |

O Rings Seal Application
Rubber washers are flat rubber rings with center holes to accommodate fasteners or allow fluids to pass through. Rubber washers prevent leaks, protect surfaces, and dampen vibration in a variety of applications. Because of their durability and flexibility, these rubber spacers provide a tighter seal than metal washers in many applications.
