Made of our hardest Viton® fluoroelastomer, these O-rings can handle sudden pressure changes that would cause softer O-rings to crack or deform. They're often used in compressed air systems or oilfield equipment, such as blowout preventers and wellhead assemblies. These O-rings are tested to NORSOK M-710 standards for rapid gas decompression and extrusion resistance.
