O-Rings
O-rings are solid-rubber seals that are shaped like a doughnut and are round in nature. When pressed between two mating surfaces, O-rings block the passage of liquids or gases. O-rings can form a static or dynamic seal. A static seal is where the O-ring does not move and is used simply for containing pressure or maintaining a vacuum. Dynamic seals can be reciprocating (like a piston and cylinder), or rotating (shaft rotating in a housing).
Allied Metrics offers o-rings in a multitude of o-ring materials and durometers ranging from 25 – 90 durometer on the shore A hardness scale.
