O-ring Sealing Principles

O-rings are bi-directional seals, circular in shape and cross section. O-rings are generally
made of an elastomeric material, but may be made of other materials such as PTFE or
metal. An O-ring seals through the deformation of the seal material by installation and media pressure to close off the gap between mating components. Higher system pressures can cause deformation through the gap, known as extrusion, resulting in seal failure. Choosing a harder seal material or installing back-up rings to support the O-ring may alleviate this problem.

VMQ (Silicone Ring):

It has good electrical insulation properties. Tensile strength is worse than the general rubber and not oil-resistant, silicone temperature-resistant range temperature:-43~210℃, the most outstanding advantage is that it has excellent high temperature resistance, anti-static properties.

Application

The O-Ring is used predominantly for static sealing applications:
- As aradial static seal, e.g. for bushings, covers, pipes, cylinders
- As an axial static seal, e.g. for flanges, plates, caps.
O-Rings in dynamic applications are recommended only for moderate service conditions.They are limited by the speed and the pressure against which they are to seal:
- Forlow duty sealing of reciprocatingpistons, rods, plungers, etc.
- For sealing of slowlypivoting,r otating or spiral movements on shafts, spindles,rotary transmission leadthroughs, etc.
