KESARIA manufactures FKM O Rings & FKM Seals, also called Viton O Rings & Viton Seals, which prevent leakage of all types of liquids, gases & oils with amazing capabilities to withstand even the most challenging environment where temperature extremes & chemical interactions are common & are suitable for use in a number of specialised domestic & industrial applications.

Kesaria Viton�® O Rings & Viton�® Seals have larger operating temperature range, better resistance to degradation from exposure to weather, ozone & UV rays, excellent resistance to heat, hydraulic fluids, oils & fuels, organic solvents & other harsh chemicals with higher durability & better operational efficiency to last longer hence reducing maintenance cost & providing a more reliable seal for longer period of time.

Kesaria Viton O Rings & Vito Seals are frequently used in Automotive, Home Applications, Chemical Industry, Pharmaceutical Industry, Oil & Gas Industry, Petroleum Refining, Agricultural Industry & many more.

O-rings are available in a wide range of sizes, hardnesses and colours. It is vital to understand what all three factors mean and how they affect applications, equipment and processes.

O-rings are available in a variety of colours, as each colour has a secret meaning. The colour can indicate the type of material on which the O-Ring is based and is set by industry standards. For many years, industry standards have been based on the common colours that come with these materials.
