The cure date identifies the quarter and year of manufacture of the o-ring (e.g., July to September of 2001 = 3Q01). The vast majority of the o-rings that are used in the MAGSEAL and MACHSEAL designs have an unlimited shelf life per ARP5316. Magnetic Seal Corp uses two o-ring elastomers that have a 15 year maximum shelf life. They are Nitrile or Buna-N (NBR) and Neoprene (CR).
