How to select cost-effective rubber seals

O-ring is a rubber ring of circular cross section, because the O-section, is called the O-ring. Hydraulic and pneumatic drive system is the most widely used one. Usually in the Taiwan enterprises, Japanese companies called O Ring.
O-ring is a ring with a circular cross-section rubber tamper seals is mainly used for mechanical components under static conditions to prevent leakage of liquids and gases in some cases. O-ring can also be used as axial reciprocating movement and low-speed rotation of the dynamic sealing element according to different conditions, different materials can be selected with suitable.
O-ring is usually used when you try to use a large cross-section of the O-ring in the same gap in the case. O-ring is squeezed into the volume of the gap should be less than it is squeeze the maximum allowable value.
Different types of fixed or dynamic sealing applications where vehicle cargo seal, o-ring provides designers with an effective and economical sealing element. o-ring is a double-acting sealing element. The installation's initial radial or axial compression, given its initial o-ring sealing capability. Generated by the system pressure and the sealing force and the total synthesis of the initial sealing force of the sealing force, which increase with the system pressure increased. o-ring seal in the static case, showing a prominent role. However, in a dynamic appropriate occasions, o-rings are often used, but it is subject to seal the velocity and pressure limits.
