  • AS568 Buna O-Rings

OneMonroe PTFE O-Rings offer exceptional reliability and durability, making them the preferred sealing solution for industries that require top-tier performance. Crafted from polytetrafluoroethylene (PTFE), a material renowned for its high resistance to chemicals, extreme temperatures, and wear, these O-rings are engineered to maintain a solid seal in even the harshest conditions. Their robust properties make them ideal for industries like aerospace, automotive, chemical processing, and food and beverage, where high precision and durability are paramount. The AS568 PTFE O-Rings are available in various sizes and meet industry-standard specifications, ensuring compatibility with an extensive range of applications and equipment.

Our PTFE O-Rings are meticulously manufactured to provide superior anti-friction and anti-stick properties, ensuring smooth operation and longevity in demanding environments. Thanks to PTFE’s non-reactive nature, these O-rings excel in applications where traditional rubber O-rings would quickly degrade or lose effectiveness. They can withstand a wide range of temperatures, from -100°F to over 500°F, and resist aggressive chemicals, including solvents, acids, and bases, which could compromise other materials. These unique attributes make OneMonroe PTFE O-Rings a highly reliable choice for applications requiring minimal maintenance and reduced downtime.

At OneMonroe, we are committed to providing high-quality sealing solutions that meet our customers’ specific needs. Our AS568 PTFE O-Rings are available in standard and custom sizes to ensure a precise fit in your applications. In addition to superior performance, our O-rings feature a low coefficient of friction, making them perfect for dynamic applications with moving parts. With OneMonroe, you can count on expert craftsmanship, stringent quality controls, and a dedication to innovation, ensuring that your equipment operates smoothly and efficiently, even under the most demanding conditions. Choose OneMonroe PTFE O-Rings for a reliable, long-lasting seal in any environment.
