What about gaskets, seals, hoses and O-ringsare they compatible with Bioheat fuel?
All known gaskets, seals, hoses and O-rings are compatible with blends of less than 20% biodiesel. For higher Bioheat fuel Blends than 20% biodiesel, up to and including 100% biodiesel, compatibility will depend on the materials they are made from. For Bioheat fuel Blend concentrations over 20% biodiesel, fluorinated polyethylene, fluorinated polypropylene, Teflon, Teflon lined, or Viton? Components are recommended. Use of other types of materials in Bioheat fuel Blends over 20% biodiesel such as nitrile, natural rubber, or Buna-N type rubbers may cause leaks, plugged filters (due to dissolved material) and eventually complete gasket, seal, hose or O-ring failure.
