O-Rings
O-rings are primarily used for sealing. Another application is the use as drive belts. As a seal, an O-ring is a means of preventing an unwanted escape of fluid or pressure. Types of seal applications include:
Static Seal
The mating gland parts are not subject to relative movement.
Dynamic Seal
- Reciprocating relative motion along the shaft axis
- Oscillating: movement around the shaft axis relative to the other member
- Rotary: movement around the shaft axis in one direction only
- Seat: mechanical distortion of the O-ring around a shaft in order to create the seal.
Pneumatic Seal
Similar to any of the ones previously described except it is used with a gas or a vapor rather than liquid.
Vacuum Seal
Seals a vacuum chamber or area.
