Are your systems protected?<\/p>\n<p>Viton O-rings are premium FKM-based seals built to withstand heat, oil, and chemicals in industrial environments. They outperform standard elastomers in durability, temperature range, and chemical resistance.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/hengoseal.com\/wp-content\/uploads\/2025\/05\/FKM-O-RING-SEAL.png\" alt=\"placeholder_image\" \/><\/p>\n<p>With more industries demanding high-performance sealing, understanding Viton O-rings is crucial. Let\u2019s explore what makes them different, where to use them, and when not to.<\/p>\n<h2>What is Viton O Ring?<\/h2>\n<p>Viton O-rings are made from <strong>FKM (fluorocarbon rubber)<\/strong>, offering exceptional resistance to high heat (up to 250\u00b0C), fuels, and aggressive fluids. These qualities make them ideal for demanding applications like automotive engines, chemical reactors, and hydraulic systems.<\/p>\n<p>Compared to standard materials like NBR, Viton offers a superior lifespan in extreme conditions. In my work with global clients, one case in Germany showed that switching to Viton seals reduced hydraulic system downtime by nearly 50%.<\/p>\n<p>If you\u2019re seeking a complete sealing solution for high-heat environments, consider this comprehensive range of <a href=\"https:\/\/hengoseal.com\/ja\/product\/fkm-o-ring\/\" target=\"_blank\">durable FKM O-Rings<\/a>.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/hengoseal.com\/wp-content\/uploads\/2025\/05\/FKM-Seal.jpg\" alt=\"placeholder_image\" \/><\/p>\n<h2>What is another name for Viton?<\/h2>\n<p>Many buyers confuse &quot;Viton&quot; with other seal materials.
