You will find that there are several types of Parker O-Rings on the market. To help you decide which one to purchase, keep in mind the following characteristics: Size, Composition, Performance, and Application. Whether you need a standard-size or custom-sized O-Ring, the Parker O Ring Distributors will have you covered. They provide the same quality and value that you would expect from other companies.
Size
A Parker O-Rings size chart is an excellent way to determine the correct O-ring size for a specific application. It includes both nominal and metric sizes, corresponding to the AS568A standard. If you don’t have access to a metric scale, you can also use a chart to determine the size. You can also consult the Parker O-rings size chart by compound number.
Parker offers standard sizes, as well as metric and neoprene/chloroprene O-rings. The table lists tolerances in millimeters and fractions of an inch for all types of O-rings, including O-rings made from these materials. For more detailed information, visit the company’s website. In addition to metric and standard sizes, Parker offers a comprehensive product catalog.
To find the correct O-Ring size, first determine the desired application. Then determine the intended size and material. The size must be smaller than the operating temperature. Then choose the material based on its hardness and tolerance. Once you have your requirements, the next step is to choose a type of seal material. Depending on the application, you can choose from various seal materials. The Parker O-Ring Selector allows you to choose between imperial and metric sizing.
Composition
What determines the performance of Parker O-Rings? The composition of an O-Ring is dependent on a number of factors, including its price, dimensional control, and temperature range. Nylon, for instance, is a relatively inexpensive option. However, the natural resiliency of an elastomer compound is crucial to the sealing process, especially during the initial squeeze. Therefore, it is crucial to choose the appropriate material for your application.
Among the available elastomers, Parker O-Rings are made of polyurethane, which is an organic polymer. This material is produced by reacting polyol with a diisocyanato, or PI. This material is widely used due to its high strength, excellent tear resistance, and excellent permeation resistance. It is also available in various compositions. Here are the main differences between the different types of O-Rings.
Nitrile O-Rings from Parker Seals and other world-class manufacturers offer excellent chemical, heat, and tear resistance. These elastomers are particularly useful for enclosed environments because they are resistant to extreme temperatures. The Hydrogenated version of NBR, however, provides greater thermal and mechanical stability. When purchasing O-Rings from Parker, it is important to choose a material with NORSOK compliance in mind.
Another factor to consider when choosing an O-ring is the compound. A good O-ring is designed to have an initial “diametral squeeze.” That initial squeeze should be minimal. To determine which O-ring buy, you can consult the Parker O-Ring Handbook. The EPM website also provides downloadable O-Ring Shadow Graphs. You can download the complete Parker O-Ring Handbook as a 3.5MB pdf file.
Performance
When you need to select an O-ring for a specific application, you may be surprised by the wide range available at Sealing Devices. Sealing Devices’ experienced application engineers are available to assist you in selecting the best product for your application. They are an Authorized Distributor of Parker O-Rings, which means you can be confident that your purchase will be high quality and durable. This company specializes in the development of advanced materials and compounds to deliver high-performance, high-strength seals to meet customer requirements. Known for its excellent tolerances and quality, Parker O-Rings are made to ensure the best performance.
Parker O-Rings performance is also enhanced by their NORSOK compliant construction. The company developed proprietary continuous molding technology to address the problems associated with sealing performance. With this process, Parker is able to design and manufacture the highest quality O-Rings available. Because of this, the company’s O-Rings meet or exceed the performance requirements of standard materials. Parker O-Rings also outperform their competitors in many applications, including those involving high pressure, high vacuum, and high temperature environments.
Another significant benefit of O-Rings is that they are cheap to produce and install. Their high-quality construction allows them to withstand a wide range of pressures and temperatures. Moreover, their memory feature allows them to retain their original shape after being squeezed under pressure. In other words, O-Rings can seal under low pressure and expand in the opposite direction when under high pressure. As a result, they are an excellent choice for a wide variety of applications, from automotive to computer.
Application
The Parker O-Ring Selector is a tool that allows you to make a highly-accurate selection of material and size. It is a comprehensive calculation platform that cover both imperial and metric standards, and it takes into account the operating temperatures and fluids pertinent to the sealing application. It also considers the hardness and conformance requirements of the seal, as well as the requirements for required approvals.
The guide contains extrusion charts showing the tolerances of O-ring materials based on temperature, total diametral clearance, and Shore hardness. It also explains how to choose proper gland designs for static and dynamic sealing. It also explains the benefits of dovetail and undercut grooves for mechanically holding O-rings during assembly or maintenance. These grooves are expensive to machine and should be used only when absolutely necessary.
In addition to neoprene, Parker also makes EPDM and NBR O-Rings. These materials are highly resistant to chemicals, abrasion, and flex cracking. Fluorocarbon (FKM) elastomers, also known as Parker O-Rings, are popular for their high-temperature resistance and chemical resistance. NSF International was founded in 1944 and is recognized by the American National Standards Institute (ANSI). The company’s O-Ring division develops products using state-of-the-art equipment to ensure reliability and quality.
