In many industrial systems, the O-ring is a small\u00a0component\u00a0but it controls\u00a0a big risk: leakage, contamination, loss of pressure, and unplanned downtime. That is why Viton (commonly referred to as FKM\u00a0fluoroelastomer) is often selected for sealing in demanding environments such as fuel handling, chemical processing, rotating equipment, and high-temperature assemblies.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">This guide explains what Viton O-rings are, how they work, what types exist, where they are used, and how to select the right grade for real operating conditions.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-ccp-props=\"{}\">\u00a0<\/span><\/p>\n<h2 aria-level=\"2\"><b><span data-contrast=\"none\">What\u00a0are\u00a0Viton O-Rings?<\/span><\/b><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;134245418&quot;:true,&quot;134245529&quot;:true,&quot;335559738&quot;:299,&quot;335559739&quot;:299}\">\u00a0<\/span><\/h2>\n<p><span data-contrast=\"auto\">A Viton O-ring is a circular elastomer seal made from a\u00a0fluoroelastomer\u00a0material (FKM).
