PTFE exhibits some unique properties when used in O-Ring sealing systems. The most well known is its impervious nature to virtually all fluids and gases from -320 °F to +450 °F. Only molten alkaline metals and certain halogenated compounds will degrade its integrity. There are no elastomeric compounds in our PTFE products. PTFE O-Rings do not have the compliance of rubber O-rings. To ease assembly, the crosssectional squeeze should be reduced relative to that specified for rubber. PTFE O-Rings generally are not subject to spiral failure as are rubber O-Rings, so gland width can be reduced. If you are concerned about the compatibility of your O-Ring seal with a sealed medium, or sealing over a wide temperature range, PTFE is one of the safest choices you can make.
