How to properly store rubber parts to maximize shelf life:

Ultraviolet light and ozone cause the most damage to rubber parts in storage. They should be stored in a cool, dark, dry place, away from direct sunlight. When properly stored, elastomers have been known to shelf age for long periods of time without losing their physical properties. The chart below indicates the generally accepted age resistance of various materials.

2-5 Years	5-10 Years	10-20 Years
Nitrile SBR Millable Urethane (polyester)	Hypalon Butyl Neoprene Chloroprene Ethylene Propylene Epichlorhydrin Millable Urethane (polyether) HNBR	Silicone Fluorosilicone Fluorocarbon Fluoroelastomer Polyacrylate

Why is it called an O-ring?

Well, it's not because of its shape. It is an O-ring because of its cross-section. There are also D-rings and V-rings.
