There are many types of O-Rings, and choosing the right one can make or break the functionality of an assembled assembly. Listed below are the benefits of NBR and EPDM rubber.

Viton(r) O-Rings
Viton(r) O-Ring is a well-known high-performance rubber material. Its properties include excellent resistance to high temperatures, oil, solvents, flame, chemicals, and ozone. Viton(r) O-rings can withstand temperatures between -40 C and 200 C. They also resist corrosion, oxidation, and UV damage. They can be used for a variety of applications including hydraulic fluids, agricultural pumps, and lawn care sprayers.

A typical Viton(r) O-Ring is available in thousands of sizes. You can order custom sizes or choose from a standard selection of three. They are available in different material types: GLT, ETP, XLT, and A. Some of the common types include Viton (R) O-Rings, FKM, GLT, and XLT. You can even choose between different material types for your needs.

Regardless of your application, you can rely on Viton(r) elastomers to withstand a range of chemicals. Both kinds of O-Rings can be used in disinfection applications. Sodium carbonate is compatible with both types of seals, but sodium hypochlorite degrades them. To determine which one is best for your application, use the Cole-Parmer Chemical Compatibility tool.

NBR O-Rings
Known as Buna-N, nitrile or NBR, is a synthetic rubber material that is widely used for o-rings, gaskets, and custom-molded components. This versatile material has many uses in a wide range of industries and applications. The following are the main uses for NBR. Read on to learn about their benefits. They are excellent for a wide range of applications.

The properties of NBR O-Rings are very good. They offer good resistance to non-polar oils, solvents, and water. The higher the acrylonitrile content, the better. They are also suitable for use in dilute acids and at low temperatures. They are not, however, suitable for applications with chlorated hydrocarbons. Listed below are some of the benefits of NBR o-rings.

The main advantages of NBR O-Rings include their low cost and excellent resistance to abrasion and tear. These rings may shrink a bit during application, resulting in leakage. But despite these drawbacks, NBR O-Rings are generally suitable for general-purpose applications. They are also excellent at working in limited temperatures but are not suitable for use with A/C.

Buna-N O-Rings are another good choice for automotive components. Buna-N O-Rings are also suited for applications involving petroleum oils, which are the primary source of oil. Their low temperature flexibility makes them ideal for applications in these industries. Although they are inexpensive, Buna-N O-Rings are not recommended for environments exposed to sunlight and harsh chemicals. However, they are an excellent choice for a wide range of applications, including a variety of automotive and aerospace pump applications.

EPDM rubber
EPDM rubber is a versatile and highly resilient elastomer that is formed from ethylene and propylene monomers. These O-rings exhibit outstanding heat and water resistance. Because of their excellent electrical insulating properties, they are ideal for outdoor use. EPDM rubber O-Rings are commonly used in applications where water, food, and other fluids must be sealed. Additionally, they are highly resistant to most hydrocarbons, including glycol.

There are several differences between EPDM O-Rings and their counterparts made of Viton. The most noticeable difference between these two types is their density. Fluorine rubber O-Rings have a density of 1.9 whereas EPDM rubber O-Rings have a mass density of 1.2. These differences in density make it easy to distinguish between the two types of O-rings. For instance, if one is burned, fluorine rubber O-Rings will automatically extinguish when removed from the fire. On the other hand, EPDM rubber O-Rings will continue to burn. These differences in performance are important in many applications.

In addition to the versatility of EPDM rubber O-Rings, their affordability makes them an excellent choice. The o-rings are black in color and available in seven sizes. These rubber O-Rings can be found in a variety of industries, including automotive, construction, and more. Depending on the application, these rubber O-Rings can be bought in bulk and easily stored for future use.
