Fluorosilicone strip, tubing, cord, “P”
seals, “U” channel and special molded
and extruded shapes are available to
MIL-R-25988 and other specifications.
This material has a superior fuel and oil
resistance combined with silicone’s
typical high temperature capabilities.
Applications included, gaskets or seals
demanding service incontact with jet
fuel, solvents, gasoline, or crude oil. This
elastomer is serviceable over a
temperature range of -60ºC to 177ºC
(-76 to 350ºF). In dry heat, the
serviceable temperature range is
extended up to 232ºC (450ºF). Physical
properties are comparable to those of
general - purpose compounds.
Dimensional designators will be the
same as “solid” silicone extrusions.
