O Ring Seal Types

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.

O ring seal types.

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. O rings are a form of gasket or seal that features a round cross section. 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. In this post we ll talk about the common types of o ring applications and their impact on o ring sizing and hardware design.

Not only can it hold up against abrasive activity it is also tear resistant. This type of seal is typically employed in the face flange type applications depicted in illustration 4 1. With a temperature scope between negative 54 and 149 c nitrile is suitable for use with hydraulic fluids petroleum and water. 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.

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. O rings are mechanical gaskets with a round cross section. Internal or external pressure must be taken into consideration when it is used as a face seal. As an aid in assessing the relative merits of an o ring the.

Some of the common types of o ring materials include ptfe nitrile buna neoprene epdm rubber and fluorocarbon viton. When designing grooves for static axial seals the first consideration is whether the pressure is coming from inward or outward. The shape can have different profiles an x shaped profile commonly called the x ring q ring or by the trademarked name quad ring. One type of o ring material.

These seals are used in flange or face type applications. This seal acts similar to the gasket which is squeezed on both ends top and bottom of an o ring cross section. They are used to prevent gas and fluid leaks in static and dynamic applications and are manufactured from various types of elastomers.
