There are many applications for O-ring seals in machines. They're often used in static settings, like cameras and refrigerators, and can also be used in scuba gear or taps. Here's a look at some of these applications. If you haven't already, check out this overview of O-ring seals.


O-Ring seals can be beneficial in a wide variety of applications, but they can also fail when the seal is not designed properly. O-Ring seal failure can result from a variety of factors, including poor design, faulty or poorly constructed glands, or human error during installation. To minimize the likelihood of an O-Ring failing, good design, and proper compound selection are essential. In addition, it is vital to test O-Rings in the actual service environment.

O-Ring seals are usually designed with a point-to-point contact between the sealing faces and the O-ring body. The point-to-point contact is advantageous in many applications because it allows high pressures to be contained while not exceeding the yield stress of the O-ring body. In addition, O-ring materials are often flexible, which helps them accommodate any imperfections in the mounting part. In addition, the surface finish of the O-ring is also an important consideration, especially in sealing parts under low temperatures.

O-Rings are generally used to seal gases and fluids. These elastomers are often exposed to high levels of temperature and pressure and must meet strict requirements for cleanliness and safety.

Type of O-ring seals

O-ring seals are used in a variety of applications, and they are commonly made from rubber or elastomer. They have several advantages, including low weight and low space requirements. They also offer excellent resistance to a variety of media and temperatures. In addition, they have a favorable price-performance ratio. There are several types of O-ring seals, including static and dynamic types. Different types of O-rings have different functions and characteristics.

The material used to make these seals also affects their performance. Synthetic rubber is a good choice for high or low temperatures, and it is suited for occasional, short-term exposure to wide temperature variations. Synthetic rubber can harden at extremely low temperatures but will regain its flexibility once it is warmed up. However, prolonged exposure to high temperatures will cause the rubber to permanently harden and lose its usefulness. However, the coefficient of thermal expansion of synthetic rubber is low enough to present a few design problems.

O-rings are available in a variety of materials, and a wide range of sizes is available. When choosing an O-ring for a specific application, it is crucial to know the material and its thickness. O-rings must meet specific tolerances for both pressures in and out. If the pressures involved are low, it is usually not necessary to follow these standards, as face seals compensate for dimensional errors.

O-ring seals Materials

When selecting materials for O-ring seals, many different factors should be considered. These include the operating conditions and the materials' specific properties. In addition, the material's temperature and chemical resistance are important factors to consider. Manufacturers should be able to help their customers determine the best materials for their specific applications.

Synthetic rubber provides excellent heat, chemical, and oil resistance. It is available in a wide range of durometers and can operate at temperatures from -20degF to 400degF. It is widely used in automotive and chemical processing applications. It can also be produced in custom colors. Other materials for O-ring seals include polyurethane rubber, vegetable fiber, and PTFE.

O-rings are a very useful type of seal, as they prevent leaks when transferring fluids. When used properly, they can make a difference in the safety of workers and equipment.

Shapes of O-ring seals

There are many different shapes of O-ring seals. Although they can be made from a wide variety of materials, their basic structure remains the same. They are looped pieces of elastomer material with a hollow center. This shape allows them to be fitted over cylindrical components.

During the manufacturing process, an O-ring is formed by pressing the material between two mold halves. The diameter of the resulting O-ring seal is a determining factor in choosing an appropriate mold. The width of the groove should be approximately 1.5 times the diameter of the O-ring itself. Modern O-ring manufacturing processes use computer-designed mold tools that can be manufactured to fit a wide range of sizes.

O-rings are also known as mechanical seals. They are used in environments involving high pressures. Because they sit in grooves between two surfaces, they can prevent gases and liquids from escaping.

O-ring Size Chart Parker

The O-ring Size Chart Parker is a useful reference for the different sizes that are available for a variety of applications. These sizes are generally used and aren't part of the AS568 line or true metric sizes. Parker's chart can be a valuable tool for those who need to replace O-ring s in their machinery.

Standard sizes

There are two main types of O-ring sizing charts: standard sizes and metric sizes. The former is the standard for the United States, while the latter is used by most other countries. Seal & Design stocks both types and can provide almost any size. Here is an overview of the two main types of O-ring sizes.

Standard size is a measurement that is considered appropriate for a particular application. You can use a Parker O-ring size chart to determine the correct size for your application. The chart provides nominal and metric sizes and corresponds to the AS568A dimension.

Metric sizes

When it comes to selecting the appropriate O-ring for your application, knowing the proper size is essential. This chart can help you make the proper selection by listing standard and nonstandard O-ring sizes. You can also obtain a free quote from an O-ring manufacturer.

To get the right size, you must know the standard and metric O-ring sizes. The standard O-ring sizes are defined by the International Standard ISO 3601-1:2002 for fluid power systems. This standard categorizes metric sizes into two separate series: G and A. The G series is used for general applications while the A series is for aerospace applications and requires tighter tolerances. There are 445 sizes in the G series and 383 sizes in the A series.


An O-ring size chart is a helpful tool that helps engineers and designers determine the correct O-ring size for a specific application. These charts list the nominal and metric dimensions of O-ring s in a variety of materials. The charts are also useful for determining the shrinkage of standard materials. Parker's O-ring Size Chart covers both metric and standard sizes.

The guide also contains information about the different extrusion methods used to manufacture O-ring s. The guide outlines allowable O-ring sizes for various fluid pressure, total diametral clearance, and Shore hardness. It also lists proper gland designs, dimensional tolerances, and surface finishes. The guide also discusses different types of grooves and undercuts used to hold O-ring s during assembly and maintenance. Some manufacturers use dovetail grooves, but these are not standard and are not as easy to manufacture as undercut grooves.


Fluorocarbon O-rings s made from different materials, and the following chart will help you determine the right size for your application. It will also provide you with metrics and nominal dimensions. These dimensions are consistent with the AS568A standard. In addition, the chart will tell you the approximate length of the ring.

The material you choose for your O-ring s is important because of its performance in varying environments. The correct material and installation methods will ensure your seals work properly. Parker offers several O-ring materials and designs that will meet your needs. Their EMG technology is highly resistant to heat, ozone, and acids.

Fluorocarbon vs. fluorosilicon

When deciding on the appropriate O-ring material for your application, you should look for materials that are resistant to certain types of chemicals. These materials are also highly versatile. They are suitable for a variety of applications, and they feature good resistance to fuel, oil, and solvents. However, they should not be used in dynamic sealing operations because of their low strength and a high coefficient of friction.

Fluorocarbon O-ring s offer excellent chemical and temperature resistance. They also have a good compression set and resilience. As a result, they are widely used in static applications. Fluorocarbon O-ring s are often referred to as "Viton" and are available in metric and nominal sizes. Fluorocarbon O-ring s can tolerate temperatures up to 450°F, making them a popular choice for the aerospace industry.
