Most O-rings I've worked with over the years are either VITON or
BUNA, trade names for compounds resitant to most stuff. Only in the
semicondutor etch world did I encounter real weird rubber compounds.
Rubber brake parts are real close to "natural" and have no noticeable
protectants/inhibitors.
The ABSOLUTE best & CHEAPEST general cleaner I use on brake jobs is
laquer thinner. It cleans ALL grease and grime off the backing
plates, springs, etc. and leaves NOTHING behind to attack & degrade
the rubber over time later on. Laquer thinner is relatively cheap
and I usually buy it in 5-gallons. It has a fairly low flash-point,
so use with good ventilation and away from a garage water heater or
other appliances that generate a good current spike when turning on
such as a garage refrigerator!

No. I used to work in the Aerospace/Jet Engines division of G.E., and
we used good ol' Vasaline on neoprene rubber O-rings throughout the
assembly of the fuel-flow transmitters that I worked on. I have never
seen Vasaline attack anything. Radiator hoses are already hot fuel and
oil resistant....to a point.
One other thing to remember though, if the hose goes on real easy
because of lubrication, it can blow off under preasure a lot easier too.
I use spit when I install new hoses.
