There are many benefits of PTFE Parker O-Rings, and choosing the right one for your application can be a daunting task. Here are some factors to consider before selecting a PTFE o-ring. PTFE is an excellent choice for sealing hydraulic cylinders and is compatible with various fluids and chemicals. To help you determine which type of PTFE o-ring choose, Parker offers several tools to assist you in the decision-making process.

PTFE Parker O-Rings are available in many sizes, and they offer the widest range. Their expert applications engineers are here to help you select the right PTFE o-ring for your application. As an Authorized Distributor for Parker O-Rings, you can count on expert guidance and superior products to meet your needs. The Parker name is synonymous with quality and high-performance.

PTFE is a flexible elastomer with excellent chemical and heat resistance. Its low compression set and good resilience make it an excellent choice for many applications, including the aerospace industry. Its low friction coefficient makes it a desirable material for a variety of applications, and PTFE is compatible with high temperatures and high pressures. In addition, it’s non-toxic, making it a popular choice for many applications.

PTFE O-Rings is also compatible with a variety of chemicals. Their low gas permeability and low absorption make them an excellent choice for harsh environments. Because of their low-price, PTFE seals are easy to apply, and their unique fillers provide specific properties. Polon” and “F” grades are used for high-speed dynamic applications, as well as in extreme pressures.


When buying Parker O-Rings NBR, there are some tips that can help you choose the right ones for your specific needs. First, consider the size of the O-Ring. This measurement reflects its inside diameter and cross-section. The size is usually indicated in decimal or fractional terms. Whether you need a smaller or larger-sized O-Ring depends on your application.

Another tip is to read the o-ring manual thoroughly. This guide will help you make a more informed decision. By reading the manual, you can make a better choice when it comes to the material and design of the o-ring. This manual will also help you choose the right type of rubber compound for your application. You can also check the Technical O-Ring Handbook for further information. Finally, always ask for a quote before you purchase Parker O-Rings NBR.

Another useful tip for buying Parker O-Rings NBR is to look for a company that has a comprehensive catalog. The company has thousands of products to choose from and will help you find the right one for your application. Parker O-Rings NBR is manufactured by Parker Hannifin, a leader in the industry. This company is known for its innovative technologies and quality standards. You can also get your hands on a full range of compound data sheets and installation guidelines for their O-Rings.

To choose a suitable product, browse the online O-Ring Handbook. This comprehensive seal catalog contains information about the sizes, composition, and certification of Parker O-Rings NBR. Once you have found the right O-Ring, check the certification of the company. If the O-Ring is certified, you can rest assured it is safe. You can also check out the company’s history.

When choosing a product, it is important to consider the chemical resistance of the elastomer. The chemical resistance of elastomers is listed in the Parker O-Ring Chemical Compatibility Chart. You can also read the O-Ring Handbook to know more about the properties of different types of elastomers. You can choose from silicone, Viton, and Fluorosilicone.


The most common material for o-rings is neoprene. The material is a versatile, general-purpose elastomer with low compression set, good resilience, and resistance to abrasion and flex cracking. Another material, called fluorocarbon, is the common trade name for viton O-Rings. These compounds offer both high temperature and chemical resistance, making them ideal for applications in the automotive and aerospace industries. Some types of viton O-Rings can withstand temperatures as low as -65°F and up to +450°F.

Another popular material for o-rings is fluorocarbon (FKM), a polymer with excellent chemical resistance and temperature resistance. Some advanced grades have superior swell resistance for use in high-octane fuel blends. Basic grades are also suitable for higher temperature and amine-based oil protectants.

Nitrile O-Rings are also available from Parker Seals and other world-class manufacturers. These compounds have excellent chemical resistance, tear resistance, and heat resistance. It is also widely used for applications in enclosed environments, like tanks and pipes. Moreover, Hydrogenated versions of NBR have greater thermal and mechanical stability. Despite their superior resistance to chemicals, it is still difficult to tell which material is the best.

Viton elastomer

For those of you looking for a high quality elastomer for your Parker O-Rings, you can find a wide selection of options from leading manufacturers. In the industry, Viton(r) is a registered trademark of DuPont Dow Elastomers. This elastomer is a fluorocarbon. It is the standard fluorocarbon technology for the Parker compound V0747-75. Learn more about the different types of fluorocarbon elastomers in the Parker O-Ring Material Offering Guide.

The best O-Ring material for a particular application depends on several factors. Operating pressure, sealing pressure, temperature, durometer, abrasion resistance, and electrical resistance are some of the key variables. The O-ring selection guide can also be helpful in determining the correct material for your application. Using the Selector tool on the AppleParker O-Ring website will allow you to choose the best material and the right size from southwest supply.

Various manufacturers offer different grades of Viton elastomer. The standard grade contains 66 percent fluorine and is commonly used for o-rings. The next grade up offers better fluid resistance, especially when it comes to fuel permeation. Custom grade materials are also available. If you have a specific application or a special elastomer requirement, consider contacting R. E. Purvis for the right solution.

In addition to polyurethane, Parker Seals also offers polyurethane O-rings. Polyurethane is a natural polymer created by reacting polyol with diisocyanate. Polyurethanes are popular for sealing applications because of their high strength and excellent permeation and tear resistance.
