ARP 5316 Elastomer Shelf Life Recommendation

The Society of Aerospace Engineers (SAE) issued Aerospace Recommended Practice (ARP) 5316. It was issued in 1998 to supersede MIL-HDBK-695 as the aerospace industry standard in governing o-rings and molded seals shelf life. ARP 5316 is often used as a guideline in determining useful shelf life of elastomers used in other industries.

Recommended Shelf life

  • 5 years: Polyurethane (millable), SBR, Natural Rubber, Polybutadine, Polyisoprene
  • 15 years: Nitrile, Neoprene, HNBR, Polyacrylate, Butyl
  • Unlimited: Ethylene Propylene, Fluorocarbon, Perfluorinated Elastomer, Silicone, Tetrafluoroethylene Propylene (Aflas®), Fluorosilicone.
