What Is the Practical Use of An O-Ring?
An O-ring is basically a circular rubber ring used to seal a connection. O-rings are one of the simplest and most reliable seal methods. This type of gasket can seal both the dynamic and static connections in a wide range of applications and industries.
O-rings are made in a variety of flexible materials such as fluorocarbon, nitrile rubber, neoprene, silicone, and polyurethane. The flexible design of this type of gasket means it is possible to retain its original shape even after being compressed. A common use for the O-ring is in the manufacturing and mechanical industries. Because the rings are relatively cost-effective to manufacture, they are a common sight in everyday items like engines and automobiles.
A connection device like a pipe is designed with a housing or groove to ensure the O-ring is kept in place. Once the ring is placed in the groove, it helps to create a reliable seal to prevent leakage between the connected items. A static connection can include regular piping while a dynamic connection is more likely to include a hydraulic cylinder. The lifespan of the O-ring can be extended in the movable joints by using a suitable lubricant. This should help to minimize the amount of rubbing and deterioration that takes place over time.
A well-mounted ring has the ability to stand up to significant pressure to prevent loss of pressure or leaks. A seal used in a hydraulic tool can prevent the loss of fluid and ensure the tool maintains the desired pressure to continue operating.
The preferred type of O-ring relates to the specific application. Certain materials are more long-lasting than others. For instance nitrile rubber is a practical choice for applications that have minimal resistance and temperature requirements. This rubber is a practical choice for general purpose seals, including certain hydraulic fluids, water, and petroleum oils. The temperature range for nitrile is in the region of 65-300 degrees Fahrenheit.
Neoprene rings have a similar temperature range as the nitrile rubber, but is more popular in air conditioning systems and refrigeration units. Polyurethane rings are quite tough with the ability to provide extrusion and abrasion resistance. This material is popular in applications like firearms, pneumatic tools, values and cylinders, and hydraulic fittings. Polyurethane can work in a temperature range of 65-215 degrees Fahrenheit. Any gasket used must match the intended application to ensure it is able to hold up to the intended workload.
