pressure, or a broad pressure range. The O-ring is usually made from a highly elastic material, such as fluorocarbon FKM. A proper stem design with an O-ring configuration requires a back-up ring or some other mechanism, usually made of PTFE, which will contain the O-ring under high pressure. In terms of temperature, pressure, and chemical attack, the design is limited by the specifications of the elastomer. Beyond issues relating to stem seal design, there are some additional causes of leaks from... (read more)
