Polymers
If you are looking for an O-ring that can handle high temperatures and aggressive chemistry, consider a Parker O-Ring. Parker O-Rings are made from a variety of polymers that offer excellent tear and dimensional stability. They are available in a variety of compounds and are highly customizable. Sealing Devices is an authorized distributor of Parker O-Rings. To learn more about the different types of O-Rings available from Sealing Devices, read below.
When choosing a seal at Southwest supply, it’s important to look for one that meets strict health and safety requirements. To achieve this, critical medical seals need to meet strict regulations, such as U.S. Pharmacopeia Class VI. These standards outline the safety and toxicity of various ingredients in medical devices. Consequently, Parker O-Rings must meet or exceed these requirements. Additionally, the materials used by the company must meet additional stringent requirements for food-service equipment.
Choosing the right material for your Parker O-Ring is essential for its durability. Various materials have different properties and prices, while others are chemically incompatible. Depending on the purpose of the product, an ideal material will depend on the temperature range, sealing pressure, and dimensional control. Nylon is a cost-effective material and offers excellent dimensional stability. Alternatively, you can consider using Kalrez elastomers from Parker. These seals feature superior performance characteristics and are FDA-compliant.
Polyurethane is another material used in making Parker O-Rings. Polyurethane is a type of organic polymer that is produced by reacting polyol with a polymeric isocyanate. The polyurethane is used widely in seals because of its superior strength, abrasion resistance, and flexibility. This makes it a preferred material for a wide variety of sealing applications.
Compounds
If you’re looking for O-Rings, you’ve come to the right place. Parker O-Rings compounds are designed to meet or exceed industry standards. Depending on the application, you can choose from a variety of compounds that range from 40 to 95 Shore A. As a Parker authorized distributor, you’ll find a large inventory of these seals and a knowledgeable team of application engineers.
NSF 61, a nationally recognized standard, sets strict requirements for compounds used in critical medical seals. NSF compounds must be non-toxic and meet stricter requirements for leachates. In addition to these requirements, NSF materials are approved for use in surgical instruments, disposable medical devices, and food-handling equipment. In addition to O-Rings, Parker offers a variety of other materials that meet these stringent standards.
Neoprene: These O-rings are generally used in applications requiring low compression set, good resilience, and abrasion and flex-crack resistance. Fluorocarbon: Also called viton, this is a great universal O-ring material. They’re commonly used in automotive fuel handling systems and aircraft engines. They’re also suitable for high temperature and hard vacuum service. Moreover, advanced grades of FKM Viton offer improved resistance to swell in high-octane fuel blends, and basic ones are suited for higher temperatures.
The properties of the compounds used in Parker O-Rings are largely dependent on the application. The primary considerations include chemical compatibility, sealing pressure, and application temperature. Other factors include size, cost, and electrical resistance. To ensure compatibility, field testing can be performed on the product. These tests help determine which O-ring material is best for a specific application. A wide variety of compounds is available. You can even try out several different types of compounds and compare them to see which one fits your needs.
Sizes
A chart for Parker O-Ring sizes is the first thing that you should look for before purchasing a new O-ring. The chart gives you the size of the O-ring in millimeters and inches, and the next column gives you the nominal size. The final column shows the O-ring’s metric dimensions. All values are in accordance with the latest AS-568 Aerospace O-ring standard.
The table also offers information on the various types of O-rings, including neoprene/chloroprene and Viton O-rings. In addition to standard sizes, the table lists the approved tolerances, or the difference between a ring’s outer diameter and its inner diameter. You can use these tolerances to compare your O-ring against a standard. A standard metric size is the most suitable for most applications.
The part numbering system of Parker O-rings helps you identify the correct size and material for your device. A detailed guide is also available online. This chart can help you determine which O-ring is best for your specific needs. Parker knows that choosing O-rings can be confusing. For this reason, it developed a tool that can help you find the right size and material. The chart can also help you select the right Parker O-ring for your application.
When choosing a Parker O-Ring size, make sure to take the ID and cross-section measurements into consideration. You can use a caliper or use a special tool to measure the cross-section of the O-ring. For the inside diameter, you can use a Pi-Tape or O-Sizer. A caliper is useful for measuring a small ID, but the cone and tape are designed for larger measurements.
Applications
The Guide to Parker O-Rings is an excellent resource for determining the correct O-ring solution. It includes extrusion charts that illustrate the allowable limits of O-rings for a given fluid pressure, total diametral clearance, and Shore hardness. The guide also discusses appropriate gland designs for dynamic and static sealing, as well as the surface finishes of O-rings. This guide also discusses the importance of dovetail grooves, which provide a mechanical means to hold the O-ring during maintenance and assembly. Dovetail grooves are highly expensive to machine, so they should only be used when they are necessary.
The Size Charts for Parker O-Rings include nominal and metric dimensions for each type of O-ring. It also provides information about shrinkage and material. Using this chart, customers can choose the size and material that best suits their needs. In addition to providing size and material charts, the Guide to Parker O-Rings includes descriptions and diagrams of the O-ring’s dimensions.
NSF 61 certification is available for Parker O-Rings. This national standard evaluates the materials used in water-delivery systems. This seal material is approved for use in the United Kingdom, Germany, and North America. NSF International was established in 1944 and has since maintained qualifications for materials used in water supply systems. The Parker O-Ring is manufacturing following the strict guidelines of NSF 61, ensuring high-quality materials and superior performance.
As with most materials, choosing the right O-ring material is crucial. Different materials have different dimensional control, chemical compatibility, and price. Depending on the type of application, the ideal O-ring material will depend on these parameters. Nylon, for example, is a very affordable material, while Kalrez elastomers produced by Parker have outstanding performance characteristics and are FDA-approved. Once you determine the exact application for Parker O-Rings, the choice of materials is easy.
