If the o-ring is made to not swell in hy-tran, I doubt if you will be successful unless it swells all other o-rings it comes in contact with as well which would not be good if it is indeed an o-ring in a transmission. Kind of guessing on his intent here from reading another post.   [Reply]  [No Email]

Just trying to pass on career knowledge of been there done that. Your answer seemed OK especially when qualified about hard burned rings. Your responses are always spot on!! Jim   [Reply]  [No Email]

Some materials will never soften once the original elasticity is lost. For most common oring materials, the shelf life is less than 10 years. I agree with Jgarner, replace it rather than try to salvage a $.50 oring. Good luck.   [Reply]  [No Email]

When an o-ring hardens it has been weakened and is no longer a vaible seal. Putting them in a "soup" to swell and soften them, and there are a number of things commercially available that will do that, only serves to make bad matters worse. Your plan IMHO is a recipe for a disasterous failure. Sorry for the negative answer but I have had too many times seen bad things happen and result in spending thousands as a result of trying to save pennies. Jim   [Reply]  [No Email]

Gasoline swells the rubber o-rings on my chain saw fill cap. Don't know what kind of permanent damage you might do to the o-ring, though.   [Reply]  [No Email]
