OVERVIEW of PTFE O-Rings

PTFE O-Rings are available from Professional Plastics.
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. PTFE is the chemically inert of the O-ring materials. It is resistant to most chemicals including acids, bases, oils, steam and other chemicals. It is also very tough and abrasive resistant. However the material is not easily compressed, and therefore may not seal as easily as some of the other polymers. Its outstanding tear resistnace 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.

O-Rings are available in sizes (sizes 0, 1, 2 and 3) which correspond to the diameter of the cross section of the O-Ring. Within these groups the O-Rings are classified according to their inside diameter.

Size 0 = Nominal Width of 0.062" (actual width = 0.070")

Size 1 = Nominal Width of 0.093" (actual width = 0.103")

Size 2 = Nominal Width of 0.125" (actual width = 0.139")

Size 3 = Nominal Width of 0.187" (actual width = 0.210")
