Differences between the black Viton (A) and the Blue Fluorosilicone fuel drain o-rings sold on this page:

  • The Blue Fluorosilicone elastomer is a Military Specification material that has a much wider temperature range than Viton (A) or Viton (B) and is widely used where fuel contains corrisive agents that are found in ULSD. Bio and veggie fuels. They will stay flexible in artic conditions down to -70º F and can withstand temperatures in excess of 400 F.
