Product description


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.

NBR (Nitrile Butadiene Rubber):

The temperature ranges apply only in connection with media that are compatible with the respective elastomers
The properties of the Nitrile Rubber depend mainly on the ACN content which ranges between 18% and 50%.
In general they show good mechanical properties.
The operating temperatures range between -30° Cand +100° C (for ashort period of time up to +120° C).Suitable formulated NBR can be used down to -60° C.
NBR is mostly used with mineral based oils and greases.


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.
