70 Durometer Blue Fluorosilicone O-rings: AMS-R-25988 Cl1 Gr 70 (M25988/1)

Fluorosilicone rubber is an inorganic "hybrid" elastomer which combines the wide temperature range spectrum of silicone with some of the chemical resistance of fluorocarbon rubber. Primary use is in fuel delivery systems. Fluorosilicone rubber offers the best low temperature properties of any oil resistant rubber. Like all compounds based on silicone rubber, fluorosilicones have relatively low tear strength, abrasion resistance, and tensile strength, and therefore, are generally not suited to dynamic applications.

Chemical Resistance:

  • Aromatic mineral oils (IRM 903 oil)
  • Fuels
  • Low molecular weight aromatic hydrocarbons (benzene, toluene).

General Information:

  • Use where excellent fluid resistance is needed at extreme low temperature
  • Typically used in aircraft fuel & hydraulic systems
  • Excellent low temperature flexibility
  • Excellent heat resistance
  • Good compression set properties

Applications:

  • Fuel injectors
  • Quick connects
  • Fuel pumps
  • Fuel tank seals
  • Any seal application dealing with fuels at low temperatures

Compound Material:

  • Blue in Color
  • 100% Virgin Materials
  • Meets Aerospace specification AMS R 25988 Class 1 Grade 70

Operating temperature: -60° to +200F° (-76° to +392C°)
