AS568 PTFE O-Rings

OneMonroe’s PTFE O-Rings are designed for applications demanding unparalleled chemical resistance, extreme temperature tolerance, and longevity. Crafted from high-quality PTFE (Polytetrafluoroethylene), these O-rings are well-suited for challenging environments that would compromise other materials. The AS568 standard sizing ensures compatibility across a wide range of applications, from industrial machinery to specialized equipment in chemical processing and food manufacturing. OneMonroe’s commitment to quality means that every PTFE O-ring offers a secure, leak-proof seal that withstands high pressures, making them indispensable for rigorous applications where performance and reliability are essential.

The unique properties of PTFE make these O-rings ideal for environments exposed to aggressive chemicals, solvents, and extreme temperatures. Unlike traditional rubber or elastomer O-rings, PTFE O-rings retain their integrity in high-temperature applications, withstanding ranges from -328°F to 500°F (-200°C to 260°C). This resilience ensures that the O-rings remain effective in sealing processes under the most demanding conditions. Additionally, PTFE’s non-stick properties mean these O-rings experience minimal friction and wear, which prolongs their lifespan and helps reduce maintenance downtime.

At OneMonroe, we understand that no two projects are identical, and our extensive inventory of AS568 PTFE O-rings provides a solution for nearly every industry need. Whether you’re working in aerospace, medical technology, or heavy-duty industrial applications, our PTFE O-rings offer reliable, long-lasting performance. We prioritize quality in every O-ring we produce, ensuring each piece delivers a precise fit and secure seal. With OneMonroe’s PTFE O-rings, you gain not only an exceptional product but also a partner committed to meeting the highest standards of excellence in sealing solutions.
