If you need a high-quality parker o-rings, you should choose one that is made of the right material for the application. You can choose from Fluorocarbon, Ethylene propylene, or Fluorosilicone. You can also use a custom-sized o-ring. ETS o-rings meet all industry standards and are manufactured according to international standards. Parker offers a wide variety of sizes to fit your needs.
Fluorosilicone
The outstanding properties of fluorosilicone O-rings have made them the preferred material for many low-temperature hydrocarbon hydraulic and aerospace applications. With three different hardness levels, they can be matched to the needs of most industrial applications. They are also ideally suited for use in semiconductor ashing equipment and aerospace applications. The following are some of the benefits of Fluorosilicone O-Rings.
As a member of the silicone family, fluoro silicone has excellent hot air resistance and improved fuel and mineral oil resistance. It is advisable to consult the Parker o-ring Handbook for the recommended media and temperature ranges. Alternatively, a Parker representative can recommend a material that suits the specific application. For a comprehensive list of benefits and limitations, visit the company’s website.
Black Fluorosilicone Parker O-rings are available in EPDM and are suitable for sanitary and heating applications. They are also available in EN 681-1 standard and feature the SECURFRABO patented security system. They are capable of sustaining low temperatures up to -10 degrees. On the other hand, green O-Rings are made from HNBR and hydrogenated Nitrile. They are especially suitable for fluctuating heat and stress.
In addition to their high-quality, affordable, and reliable, Fluorosilicone Parker O-rings have a low cost of ownership and easy mounting. They are highly durable and can be reused time again. Their long lifespan matches their useful life. This is an important factor in the selection of Fluorosilicone Parker O-Rings. They are a cost-effective alternative to crush-type gaskets.
Fluorocarbon
In recent years, the use of fluorocarbon in Parker O-Ring products has increased. These materials are used for a variety of applications, including medical devices, surgical instruments, and food and beverage equipment. This material is safer than standard materials and is approved for use in a number of countries, including the U.S., Europe, and Canada. Parker’s O-Ring Division develops a range of materials that meet these standards.
The main components of fluorocarbon o-rings are vinylidene fluoride (VF2) and hexafluoropropylene (HFP), both of which contain about 66% – 70% fluorine. Other components are added to the material to provide different properties. For example, perfluoroethylene improves chemical resistance, while perfluoro methyl vinyl ether increases low-temperature properties. Fluorocarbon o-rings are not ideal for dynamic applications, as they can become brittle and fail.
A good quality o-ring should have excellent chemical and temperature resistance. The Fluorocarbon in Parker O-Rings can withstand a broad range of chemicals, from abrasive materials to extremely high temperatures. These O-Rings are compatible with many different types of fluids and gases, including hydraulic oils and ozone. The most common types are used in lubrication applications, while a few have special applications.
Fluorocarbon is a great general-purpose elastomer, with excellent resistance to oil-based fluids and greases. Fluorocarbon is also commonly referred to as Viton, and a combination of these compounds gives it outstanding high-temperature and chemical resistance. It is a versatile material that is widely used in the aerospace industry. Despite its high-temperature resistance, it also has good low-temperature flexibility.
Polyurethane is another popular material used for Parker O-Rings. This organic polymer is formed by reacting a monomer of ethylene with a polymer of propylene or diisocyanate. This polymer is used widely due to its superior strength and excellent permeation and tear resistance. In addition, polyurethane is less expensive and easier to process than a polymer like Nitrile and has a low-tacky feel.
O-rings are essential parts of heavy equipment, such as cars and trucks. These O-ring seals prevent fuel from spilling and facilitate pressure transfer in combustion chambers. The reliability of these seals depends on how they are installed and what materials they are made of. When choosing your O-rings, you can consult with professionals to ensure the right fit. Wyatt Seal carries a range of O-rings for a variety of applications.

Ethylene propylene
EPDM or ethylene propylene is a common material used in o-rings. This type of rubber is known for its compatibility with a wide range of solvents, including phosphate-ester hydraulic fluids. EPDM is especially useful for securing components in brake systems that use glycol-based fluids. Here are some of the benefits of EPDM.
The EPDM material is used for many industrial applications. It has a high resistance to steam and is an excellent general-purpose elastomer. It is also abrasion, flex cracking, and chemical-resistant. EPDM Peroxide-cured O-rings are more expensive, but they have the same properties as sulfur-cured rubber. They are both resistant to heat, steam, alcohol, and other chemicals.
The elastomeric materials used in elastomeric O-rings are designed to provide outstanding sealing performance in nearly every type of seal application. Whether static or dynamic, these O-rings are recommended for use in a wide range of industries. The process used to manufacture these O-rings includes in-house elastomeric mixing, computer-controlled compression molding, liquid injection molding, and automated vision inspection.
Ethylene propylene rubber is an elastomer made from ethylene and propylene monomers. This material can withstand temperatures ranging from -50degC to +120/150degC, depending on the curing system used. EPDM is largely accepted in water and mild acidic solvents. It is also suitable for hydraulic fluids based on phosphate ester. The disadvantages of EPDM compounds include poor compatibility with oils.
