With Bio-Syn EHC Fluid, it is not necessary to utilize expensive seals, hoses, or accumulator bladders such as Viton or Teflon, as is the case with phosphate esters. Bio-Syn EHC Fluid does not have any tendency to either swell or delaminate more conventional elastomers, such as high nitrile or Buna N; but will, maximize the long term integrity of existing Viton and Teflon seals and hoses.
