AS568-024 High-Performance PTFE (Teflon®) White 55 Shore D O-Rings

Unmatched Chemical & Temperature Resistance for Extreme Sealing Applications

When your sealing application demands exceptional chemical resistance, high heat stability, and low friction, PTFE (Polytetrafluoroethylene) O-Rings provide an unparalleled solution. The O-Ring Store LLC offers precision-cut, White PTFE O-Rings designed for the most demanding environments, including chemical processing, medical applications, food and beverage, and high-friction sealing surfaces.

Unlike traditional elastomers, PTFE O-Rings do not compress easily, making them ideal for dynamic and extreme chemical exposure applications. They are the most chemically inert O-Ring material available, resistant to acids, bases, oils, steam, and aggressive chemicals. Their exceptional wear and abrasion resistance make them ideal for valves, mass spectrometer probes, and sliding applications.

Thermal & Dielectric Properties

PTFE is one of the most thermally stable plastic materials available. At 260°C (500°F), it maintains nearly all of its original properties, ensuring reliable sealing performance. Its dielectric properties make it an excellent insulator, while its low thermal conductivity enhances sealing efficiency.
