O Ring Seal Types

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.

O ring seal types.

The shape can have different profiles an x shaped profile commonly called the x ring q ring or by the trademarked name quad ring. Not only can it hold up against abrasive activity it is also tear resistant. Buna n also know as nitrile o rings are one of the most common general purpose type of seal available on the market today. Internal or external pressure must be taken into consideration when it is used as a face seal.

This type of seal is typically employed in the face flange type applications depicted in illustration 4 1. 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. This seal acts similar to the gasket which is squeezed on both ends top and bottom of an o ring cross section.

These seals are used in flange or face type applications. In this post we ll talk about the common types of o ring applications and their impact on o ring sizing and hardware design. 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 a form of gasket or seal that features a round cross section.

O rings are mechanical gaskets with a round cross section. One type of o ring material. 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. 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.

O ring and other sealing profiles for sealings there are variations in cross section design other than circular. 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. With a temperature scope between negative 54 and 149 c nitrile is suitable for use with hydraulic fluids petroleum and water.
