What is Rubber Swell? Things you must know about Rubber Chemical Compatibility.

How do you make rubber flexible again?

If the component is already beyond its expected life span, you can use a hair dryer, set the rubber in an oven at 100 degrees Fahrenheit for roughly 10 minutes or even submerge the rubber in boiling water for 20 to 30 minutes to restore flexibility to the rubber and extend its usefulness.

Does gasoline dissolve rubber?

Tire compounds are made up of a combination of natural and synthetic rubbers, as well as carbon black and other chemicals. This makes their rubber compounds susceptible to damage from direct contact with gasoline, oil and antifreeze, as well as solvents often found in family garages.

What can destroy rubber?

In general, the majority or rubber types can be affected by: strong oxidizing agents (to the extreme of being irreversibly destroyed); aromatic and chlorinated hydrocarbons (both have a tendency to soften rubber).

This would include Vaseline. While Vaseline and other petroleum products may degrade real rubber (actually made from the rubber tree), current o-rings technology does not use natural rubber.

Does acetone soften rubber?

Acetone will evaporate very quickly so what ever happened probably just affected the outer surface unless you actually soaked it in the liquid. Acetone will eat rubber and certain other plastics.
