AS568 Fluorosilicone O-Rings

OneMonroe Fluorosilicone O-Rings are engineered to provide exceptional sealing performance, especially in demanding environments that require resistance to extreme temperatures, chemicals, and other aggressive agents. Manufactured to AS568 standards, these O-rings are designed with precision to ensure a secure, leak-proof seal in a wide range of applications, from aerospace and automotive to industrial machinery and chemical processing. With their unique fluorosilicone material, OneMonroe O-Rings offer superior resistance to fuels, oils, and solvents, making them a reliable choice for critical applications where other materials may fail.

In addition to chemical and temperature resistance, OneMonroe Fluorosilicone O-Rings provide excellent durability and stability over prolonged use, even in variable environmental conditions. Their resilience against both high and low temperatures makes them ideal for applications that require flexibility and strength, ensuring that seals remain effective and secure. Whether for use in high-pressure systems or equipment exposed to outdoor elements, these O-rings maintain integrity and performance, reducing the need for frequent maintenance and replacements, which saves time and costs over the long term.

At OneMonroe, we understand the importance of quality and reliability in industrial sealing solutions. That’s why our Fluorosilicone O-Rings are crafted with precision and held to rigorous quality standards. Each O-ring undergoes thorough testing to guarantee its performance in the most challenging applications, providing peace of mind to engineers and operators alike. With our commitment to delivering superior products, OneMonroe Fluorosilicone O-Rings offer the quality, resilience, and endurance required for complex and critical sealing needs, making them a trusted choice for industries that demand the best.

This elastomer possesses mechanical properties similar to Viton®, with the exception of its slightly lower compression set resistance. It is more suitable for sensitive applications where lighter compressive forces are applied to energize the seal. This core has a Shore A hardness of 70 but it also offers a broader operating temperature range of -80°F to +500°F. (-62°C to +260°C).
