Proper storage of elastomer seals and gaskets is critical for maintaining their performance over time. Per ISO 2230 guidelines: temperature 15-25°C (avoid extremes — cold causes crystallization in neoprene, heat accelerates aging); relative humidity 50-70%; no direct sunlight or UV (causes surface cracking in NR/SBR); no ozone exposure (keep away from electric motors, welding equipment, mercury vapor lights); no deformation (store flat or on mandrels, never hang O-rings on hooks/nails); no contact with metals (especially copper and manganese which catalyze degradation). Shelf life: NR/SBR 5-8 years, NBR/EPDM/CR 8-10 years, silicone 10-15 years, FKM 15-20 years, PTFE indefinite (no aging). First-in-first-out (FIFO) inventory rotation. Label each bag with material, size, date received. Per ISO 2230 and DIN 7716 for rubber storage.
