About the chemical resistance of polycarbonate
The chemicals in the following table degrade polycarbonate. Because of this, they may damage the bowl of the filter regulator or the
front cover of the pressure gauge and cause an accident. The products cannot be used in locations where the chemicals in the following
table are present in the compressed air, ambient air, or on surfaces. This does not mean that polycarbonate is chemically resistant to all
chemicals not listed below.
