HOW O-RINGS WORK:

O-Ring Description
An O-Ring is a torus, or doughnut-shaped object, generally made from an elastomer like Nitrile or Fluorcarbon, though O-Rings can be made in PTFE and other plastic materials, and in metals, both hollow and solid. They are used primarily for sealing. Another use is for light duty drive belts.

Basic O-Ring Principles
An O-Ring gasket is a means for closing off a passageway preventing an unwanted escape or loss of fluid. The seal consists of an O-Ring installed in a gland and is exactly that - a circular run in which the elastomeric material has a section that is virtually a circle. The gland is the cavity (usually within metal) into which the O-Ring is placed. The combination of these two elements comprises an O-Ring seal.

O-Ring Operation
All fluid-tight seals are characterized by the absence of any passage by which fluid might escape. Detail differences exist in the manner by which zero clearance is obtained - welding, brazing, soldering, ground or lapped fits or the yielding of a softer material wholly or partially confined between two harder and stiffer members of the structure. The O-Ring seal falls in the latter class. The rubber seal should be considered as an incompressible, viscous fluid having a very high surface tension.

How To Order O-Rings
When you order, http://www.epm.com needs to know the inside diameter (I.D.), the cross section diameter (W), and the compound (rubber material) from which it is to be made, these three pieces of information being sufficient to describe an O-Ring completely.
