What are PTFE - Teflon O-rings?

PTFE (polytetrafluoroethylene) - Teflon O-rings are sealing rings made from PTFE, a fluoropolymer known for its excellent chemical resistance and low friction coefficient. PTFE is inert to most chemicals and can withstand extreme temperatures ranging from -200°C to 260°C.

PTFE O-rings exhibit low friction, allowing for easy movement and minimal wear. They resist oil, water, acids, bases, and many solvents. PTFE - Teflon O-rings are commonly used in applications requiring high chemical resistance, such as in the chemical processing industry, pharmaceutical industry, food industry, and laboratory equipment. The unique properties of PTFE make it a versatile choice for seals operating under extreme conditions and with aggressive media.

Properties of an PTFE O-ring

PTFE - Teflon O-rings possess unique properties that make them suitable for demanding sealing applications. Firstly, they offer excellent chemical resistance against a wide range of chemicals, including acids, bases, solvents, and oils. PTFE O-rings are inert and do not react with most substances, making them ideal for use in chemical processing and laboratory environments.

Additionally, PTFE O-rings have very low friction, allowing for easy movement and minimal wear. They withstand extreme temperatures ranging from -200°C to 260°C without losing their mechanical properties. PTFE O-rings are also non-porous, making them easy to clean and sterilize, thus suitable for use in the food and pharmaceutical industries. In summary, PTFE - Teflon O-rings provide durable, reliable sealing in demanding environments with chemical and thermal challenges.

Applications of PTFE - Teflon O-rings

A PTFE O-ring finds numerous applications in industries where reliable sealing against chemical and thermal influences is essential. They are commonly used in chemical processing plants to seal pumps, valves, and pipes against aggressive chemicals and solvents. In the pharmaceutical and medical industries, PTFE O-rings are used due to their inertness and biocompatibility.

Furthermore, PTFE - Teflon O-rings are suitable for food processing equipment, where they withstand temperatures and cleaning agents. In aerospace, they are used for sealing applications under extreme temperatures and vacuum conditions.
