1. Description:


Sealing Performance:


PTFE O-rings exhibit outstanding sealing capabilities, ensuring leak-free connections in various applications. Their unique composition provides excellent resistance to chemicals, solvents, and corrosive substances. The low coefficient of friction of PTFE minimizes frictional losses, allowing for efficient sealing even under high pressures.


The superior elasticity of the O-ring design enables it to effectively seal both static and dynamic applications, accommodating variations in temperature and pressure. With exceptional resilience and durability, PTFE O-rings maintain their sealing integrity over extended periods, ensuring reliable performance in demanding environments.

Insulating Performance:
PTFE O-rings possess exceptional electrical insulating properties, making them ideal for applications that require electrical isolation. With a high dielectric strength and low dielectric constant, they effectively prevent the flow of electrical currents. This insulating capability makes PTFE O-rings suitable for use in electrical connectors, switches, and other components, where reliable electrical insulation is critical. Furthermore, PTFE's resistance to high temperatures ensures that the O-rings maintain their insulating performance even in demanding thermal environments. With their superior insulation characteristics, PTFE O-rings provide reliable protection against electrical leaks and shorts.
In summary
PTFE O-rings offer exceptional sealing performance, ensuring leak-free connections, while also providing excellent electrical insulation. Their chemical resistance, elasticity, and durability contribute to their sealing effectiveness, making them suitable for various applications. Simultaneously, their high dielectric strength and insulating properties enable them to prevent electrical currents, ensuring reliable electrical isolation in diverse electrical systems.
