The ATF fluids were less destructive with the two seal compounds at the temperatures investigated. The non-ATF fluid tended to extract unattached and un-bonded compounding ingredients from the rubber matrix. This leads to excessive shrinkage, increasing hardness, reduced lip flexibility, reduced interference and seal leakage. References (1.) L.R.G.
