To those overhauling ABC valves - you need these o-rings
Fluorosilicone (FLS or FVMQ) O-Rings
Sizes: AS568 sizes 7, 8, 9, 10, 12
They are in blue color and typically used in aerospace applications. You need them if you plan to use Pentosin CHF 202 interchangeably with Pentosin CHF 11S Because Pentosin 202 has heavily-hydrogenated neutral oils. Yeah the green color is just a die to differentiate from other oils.
Neoprene, SBR Rubber, Low Nitrile Buna N are not recommended
To those who want to nitpick:
(Both have high viscosity index but 11S is slightly better, I've been using 202 on my cars for both steering and ABC without issues, 202 is slightly cheaper for some reason)
CHF 11S
Product Attributes
Appearance Dark Green
Density at 20°C 825 kg/m³
Kinematic Viscosity at 100ºC 6.0 mm²/s
Kinematic Viscosity at 40ºC 18.7 mm²/s

Viscosity Index 313
Pour Point -57°C/-70.6°F
Flash Point 160°C/320°F
Ignition Temperature 235°C/455°F
CHEMICAL FAMILY: Blend of synthetic hydrocarbons, additives
and dye.
CHF 202
Product Attributes
