O Ring Seal Types

O ring and other sealing profiles for sealings there are variations in cross section design other than circular.

O ring seal types.

They are used to prevent gas and fluid leaks in static and dynamic applications and are manufactured from various types of elastomers. Not only can it hold up against abrasive activity it is also tear resistant. In this post we ll talk about the common types of o ring applications and their impact on o ring sizing and hardware design. With a temperature scope between negative 54 and 149 c nitrile is suitable for use with hydraulic fluids petroleum and water.

Internal or external pressure must be taken into consideration when it is used as a face seal. They are commonly used to prevent leaks of either fluids or gases from occurring in products systems or machinery and find use across a variety of industries. Nitrile o rings are a popular type of rubber seal gasket that s used in a wide range of applications and environments they re broadly seen as a general purpose o ring type with reasonably resistant sealing properties against water gasoline petroleum oils crude oil propane and some hydraulic fluids. This type of seal is typically employed in the face flange type applications depicted in illustration 4 1.

As an aid in assessing the relative merits of an o ring the. When compared with an o ring these other seal types may show one or more design disadvantages which might be overcome by use of an o ring. A number of common seal types t seals u cups v packing and other devices have been and are still used for both dynamic and static seals. O rings are mechanical gaskets with a round cross section.

These seals are used in flange or face type applications. The shape can have different profiles an x shaped profile commonly called the x ring q ring or by the trademarked name quad ring. Widely regarded as a general purpose type of o ring nitrile elastomers also known as buna n or nbr offer a respectable temperature range of between 50 c and 120 c with excellent resistance to tears and abrasive treatment. This seal acts similar to the gasket which is squeezed on both ends top and bottom of an o ring cross section.

Static axial seals a static axial seal acts similar to a gasket in that it is squeezed on both the top and bottom of the o ring s cross section. When designing grooves for static axial seals the first consideration is whether the pressure is coming from inward or outward. O rings are a form of gasket or seal that features a round cross section.
