Why the Industries can’t Function without O-Rings

O-Rings are the most basic of all components required to keep components together in any present-day machinery. The O-rings are the basic keeping-the-cog-together elements in any given industry system. They are responsible for preventing leakages and slip and keep two machine parts from being disjointed. The machinery functional in any manufacturing or storage plant today is made up of smaller, unit cogs that are joined together at the ends. The O-rings are responsible for securing these joints. From pipelines in a petrochemical plant to the space shuttle nose cone, O-rings are playing their due part everywhere in the manufacturing sector. Especially in the one associated with the infrastructural development.

Keeping in mind the multi-dimensional usage of the ubiquitous O-rings, the manufacturing industry is now building O-rings of different designs, shapes, and sizes. And those from different materials as well. Need is the mother of invention and as newer avenues for the use of O-Rings in modern machinery are discovered, the need to manufacture suitable O-rings develops as well. And that is why perhaps while the O-rings used to be all round shaped a few years ago, now they can be found in the solid square and the strong, gripping cross triangle even. Some O-Rings are designed to close upon the joins and hold them firm in their clutch. Many different designs like that of the x-ring have been experimented with as well.

Apart from the designs, the variations can also be found in the materials used for the production of O-rings. There are rubber based O-rings meant to seal the underwater machinery which can’t use the rust-prone iron and those that might require high elasticity. Buna-N and Buna-S are used to manufacture these O-rings. Then there are systems that need to be highly heat-resistant. Silicon is the perfect material to produce heatproof O-rings that find use in many high-end applications. Similarly, SBR, NBR, Kalre, EPDM, PTFE, and Aflas O-rings can be found which all have a rubber base.

The sizes of all O-Rings manufactured in the market are determined by American standards, The British Standards, and the Japanese standards depending on the manufacturer. Many O-Rings in the market are available in sets and kits that contain O-rings of the same material in different sizes. A Viton O-Ring, however, should always be selected keeping in mind the job that is required to be performed with the help of it.
