FILL FLUID
SPECIFICATIONS –
INERT (HALOCARBON)
Halocarbon Description
Halocarbon is the Inert Fill offering with our remote seals. Halocarbon 4.2 fill
fluid refers to the viscosity in centistokes at 100 °F. It is essentially
non-reactive to a wide range of chemicals, including halogens, oxygen, and
other specialty gas applications. Other applications to consider Halocarbon
include those in which silicone fluids are banned due to product contamination
problems (i.e. paint manufacturing). It’s higher vapor pressure than standard
Silicone 200 silicone does restrict applications, especially if vacuum service. It
should not be used for Food Grade applications. CTFE oils are available in
various viscosity from 0.8 cSt to 1000 cSt at 1000 °F. Halocarbon 0.8 cSt is
available as a 1199 special fill fluid mainly for cryogenic applications. The 0.8
cst fluid ASTM D97 Pour Point is –200 °F. Halocarbon 27 cSt is also available
for vacuum services that cannot use silicones.
