Oringi PTFE Teflonowe
They are made of flexible material with a circular cross-section. Thanks to their versatility and unique advantages, they fit into the needs of various industries – from the aerospace industry, through food, radio, microwave, pharmaceutical and telecommunications. PTFE orings are distinguished by their extremely low coefficient of friction, abrasion resistance, ozone and weather conditions, and almost complete chemical resistance. In addition, they are an electrical insulator and are also great for dynamic applications. They can withstand temperatures from -200 °C to +250 °C.
These features make the PTFE o-ring an extremely desirable product for a wide range of applications. It is an economical alternative to FFKM materials. However, there are some limitations to keep in mind: low compression and sensitivity to alkaline metals, sodium, potassium, hydrogen fluoride and fluorine gas exclude the possibility of using the product in some cases. However, with the huge advantages of the material, the number of defects is a marginal value.

What are the properties of PTFE Teflon® O-rings?
PTFE (Teflon) O-rings are seals with exceptional chemical and mechanical properties, used in demanding industrial applications. PTFE is characterized by its outstanding resistance to aggressive chemicals, solvents, and high temperatures, making these O-rings suitable for use in the chemical, food, and pharmaceutical industries. With a low friction coefficient, they minimize wear and eliminate the risk of sticking to surfaces. They are resistant to pressure and have a wide temperature range from -200°C to as high as +260°C. Their lack of elasticity compared to elastomers is compensated by their resistance to aging and moisture absorption. These O-rings are an ideal choice for applications requiring sterility, chemical resistance, and dimensional stability.
Application of Teflon O-rings
PTFE O-rings are seals with high chemical and temperature resistance, widely used in advanced industrial applications. Thanks to their exceptional chemical inertness, they are used in the chemical industry, effectively protecting installations from aggressive substances such as acids, bases, or solvents. In the food and pharmaceutical industries, PTFE O-rings guarantee sterility and lack of interaction with media, making them an ideal solution for pumps, valves, and reactors. In the energy and petrochemical sectors, they are used in high-pressure installations, where they must withstand extreme temperatures from -200°C to +260°C. PTFE O-rings are also utilized in hydraulics and pneumatics, especially where traditional elastomers degrade. Their low friction coefficient makes them indispensable in dynamic applications that require precise sealing and long life.
What are the benefits of using PTFE O-rings?
PTFE (Teflon®) O-rings offer exceptional hermetic sealing, effectively eliminating the risk of leaks and ensuring reliability in demanding applications. Due to its molecular structure, PTFE exhibits extraordinary resistance to aggressive chemicals and high temperatures, allowing these O-rings to maintain tight seals even in the most extreme conditions. The high flexibility and ability to conform to surface irregularities make PTFE O-rings excellent for sealing, minimizing fluid losses and protecting equipment from contamination. Additionally, the low friction coefficient of PTFE contributes to the longevity of seals, reducing operational and maintenance costs. Perfect for use in industries such as chemical, food, or pharmaceutical, PTFE O-rings provide hermetic sealing even in the most challenging applications.
