O-Rings

An O-ring is a cost effective, light weight doughnut shaped, molded ring made from an elastomer, can also be made of PTFE, and other plastics and metals. O-rings are used for sealing to prevent loss of fluids or gas. Some O-rings have a life expectancy referred to as “shelf life” that corresponds to the O-ring material.
