Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this silicone O-ring boasts an inside diameter of 2.657 inches, an outside diameter of 0.520 inches, and a cross-section of 0.158 inches. The inherent flexibility and wide temperature range of silicone (-60°C to 230°C) are enhanced by the integrated nylon reinforcement, which provides increased tensile strength, tear resistance, and dimensional stability. This combination makes it ideal for applications requiring resistance to moderate pressures and aggressive media, ensuring a secure and long-lasting seal where standard silicone may degrade or deform.
