PTFE is a popular O-Ring material which is White in color. The PTFE O-Rings are popular for use in applications which require a chemically resistant and non-compressible material.
Our PTFE O-Ring 1.AS568 US standard and other sizes 2.OEM Services are available There are several different standards to choose from when it comes to O-ring dimensions. The most popular in the United States is the AS568 standard for O-ring sizes and tolerances. Maintained by the Society of Automotive Engineers, this standard allows the user to choose from five different cross-sections with inside diameters ranging from 1/32" to 26".
All Seals also offers a wide array of metric sizes, in both standard and non-standard dimensions. All Seals can provide custom O-rings, specially made to your demanding requirements.

PTFE is the chemically inert of the O-ring materials.
> Resistant to most chemicals including acids, bases, oils, steam and other chemicals.
> Very tough and abrasive resistant.
> Has minimum friction coefficient of all know pure material > Non-viscous, no aging > Now molds can be made according to customers requirements.
However the material is not easily compressed, and therefore may not seal as easily as some of the other polymers. Its outstanding tear resistance and abrasive resistance result in its slippery surface properties that make it advantageous for use in seals in moving systems such as mass spectrometer probes and valves.
