These seals are made from a special Viton compound and can resist higher temperatures than regular Viton seals. It is strongly recommended to install these seals with AV&V valve seal drivers as these allow easier and more precise installation of both OEM or Viton valve seals. The valve seal is installed in centerline with the guide, preventing the seals from coming loose.
