The Prescollan (TM) or Vulkalan washers I used for these exotic cars seemed to have a short shelf life and and even shorter life on the car. So we developed a new version, similar in looks and quality but with much better physical properties. These are made of Carboxylated Nitrile Butadiene (XNBR) (Superior to Buna (TM); have the same appearance, same Shore hardness and when installed correctly will not fall out or disintegrate like the OEM ones.
