Parker o-rings are highly recommended when tight and leak-free sealing is a concern. These little seals are used in some of the most critical applications and they have gained immense reputation for providing an exceedingly secure fit. Much of the reliability of these seals comes from the fact that they are made using a high-quality elastomer that can handle pressure, vibration, and varying temperatures with ease.
Specifications of o-rings
As the name implies, o-rings are shaped like a donut. In addition to be used as sealing rings, these components have also been used as a mechanical drive belt in light-duty applications. These could be manufactured using either natural rubber or synthetic rubber. They are widely used across the world to prevent leakages in applications that deal with the storage or transportation of fluids and gases.
If zero-leakage is a high priority, then the use of o-rings is strongly recommended. The best part about o-rings is that they are elastic and can bend according to the shape of a groove or cavity. Thus, these components offer a very snug fit and minimize the risk of leakage or seepage.
They are available in a myriad of sizes, thicknesses, materials and hardness ratings to meet all types of sealing requirements. In fact, some rings are designed in a manner to endure pressures up to 1000PSI. These are often used in conjunction with well-fitting gaskets.
Applications of Parker o-rings
Each industry type uses different o-rings standards that are manufactured according to unique industry specifications. For instance, in the USA, the design, safety and standardization of o-rings is supervised by the SAE. These rings are used in the food and beverage industry, transportation of goods, aerospace sector, high pressure systems, and so on.
These rings also find usage in vacuum-based applications. However, the ones used in high vacuum systems could be made of materials such as copper and nickel as opposed to rubber. In some cases, these rings are also used along with parker adhesives and sealants. They are available in low, medium, and high viscosity. Parker adhesives and sealants are available in variants such as instant adhesives, retainer compounds anaerobic adhesives, and thread-locker anaerobic adhesives.
When it comes to high temperature and extremely high pressure applications, piston seals are a better option as compared to o-rings. In fact, piston seals are also the recommended product for high-pressure hydraulic operations.
Benefits and advantages of Parker o-rings
The best part about parker o-rings is their versatility. They can be used with a wide range of pressures, temperatures, and tolerances. Once they are fixed, further tightening is not required. This reduces the time and energy spent on maintenance.
They are very lightweight and since they are flexible, they consume very less space during installation and thereafter too. They do not fail easily and their failure is easily noticeable prompting a quick changeover.
