When it comes to selecting Parker o-rings, it can be confusing. Luckily, there are some key tools to make your decision easier. Parker knows that a wide range of options can make your decision-making process a bit overwhelming. Listed below are key tools to help you choose the best option for your application. Once you’ve decided on your desired size, you’ll need to know the chemical and physical compatibility of your chosen o-ring.
Chemical compatibility chart
Depending on the chemical media, O-rings may exhibit a variety of signs. These signs can range from cracks and blisters to a change in hardness or colour. Some chemicals will react with specific elastomers, resulting in increased cross-link density and a hard material, while others will cause a softer, tacky material that loses its shape.
Parker Hannifin uses 70 durometer hard nitrile for its standard O-rings. For adapters and tube fittings, it offers 90 durometer nitrile. Buna-Nitrile is a popular choice among seal experts because of its competitive price and excellent resistance properties. EPDM, on the other hand, exhibits excellent resistance to heat, water, oxygenated solvents, sunlight, and mild acids. The experts suggest avoiding utilizing EPDM for applications involving gasoline and other hydrocarbon environments.
Neoprene is a versatile material with low compression set and good resilience. The elastomer is also abrasion and flex-crack-resistant. Fluorocarbon O-rings are also popular and are known as viton. FKM O-rings have both high temperature and chemical resistance and are ideal for automotive and aerospace applications. Parker FKM Viton compounds can withstand temperatures between -65°F and 450°F.
Size chart
If you’re unsure what size Parker o-rings should be for your application, use the Size Chart to help make the proper choice. This guide includes metric and nominal dimensions, as well as information on the size of standard shrinkage materials. You can also find more detailed specifications for the different Parker o-rings that are available, such as the AS568A standard. This sizing chart is an invaluable tool for design professionals, engineers, and consumers alike.
Using the o-ring size chart will help you understand which size you need, and which one will fit best. Parker offers a Parker O-Ring Selector tool to help you find the best o-ring size and material for your applications. A good selection will ensure the most effective fit for your product. If you don’t know how to use a size chart, you can also try the Parker O-Ring Selector, an excellent tool to help you determine what size and type of o-ring will fit your needs.
The Size Gauge is a handy tool that is available from the Parker Seal Group. This unique device consists of a plastic cone with a special base and a separate pi tape. These tools are used to measure the inside diameter of Parker o-rings to the nearest standard Parker Seal two-dash size. The chart is not the actual size of an o-ring; it is a guide for design and material selection.
Compounds
When developing new O-ring compounds, Parker tests them extensively. The company uses a Controlled Batch Identification (CBI) program and state-of-the-art technology to ensure quality and consistency. O-rings produced with this technology have high compatibility and resistance to both ozone and UV radiation. They can be used in closed and undercut housings and are available in a variety of sizes. Parker uses silicone for many of its O-rings, but these are not suitable for dynamic applications.
O-rings from Parker come in metric and standard sizes, as well as a wide variety of compounds. The main purpose of these seals is to prevent the leakage of liquids, gases, or other materials. They are used in static and rotary applications, complementing gaskets and seals. To learn more about the many different compounds, contact an authorized Parker Sealing Technology Center. These certified, factory-direct suppliers will be happy to assist you.
The materials used by Parker’s O-Ring Division include PTFE, EPDM, and Buna-Nitrile elastomer. PTFE offers excellent resistance to oxygenated solvents and water, while EPDM exhibits excellent resistance to sunlight and mild acidic solvents. However, experts do not recommend using PTFE seals in petroleum-based environments or around gasoline or other hydrocarbon-based compounds.
Sizes
Parker O-rings are used in many industries. In aerospace, fluid power, and semiconductor applications, they provide reliable seals for a variety of purposes. Wyatt Seal carries a full line of Parker o-ring sizes and offers many other types of elastomers, including Kalrez(r) elastomers that perform uniquely in harsh processing environments. These O-rings meet FDA and CSA standards and are also FDA-compliant.
The Parker Size Gauge is an exclusive device that Parker uses to determine the correct o-ring size for its products. The size gauge consists of a specially designed plastic cone, separate pi tape, and a special base for measuring o-ring sizes. It does not measure actual sizes, but rather the nearest standard two-dash size. Both the cone and tape are marked properly, and can be used for both metric and standard sizes.
Parker makes a wide variety of O-ring sizes and compounds to meet the specific requirements of a variety of applications. The metric and standard sizes are available, as well as custom-sized O-rings. Parker also offers a wide range of elastomeric seals for high-pressure applications. Parker also offers a variety of accessories, such as sizing cones and assembly greases.
Custom o-rings
When you need a custom O-ring, you should work with a trusted manufacturer like Parker. Providing exceptional design, expert engineering, and value added services is their specialty. In addition to world-class manufacturing facilities, they employ expert technicians to meet your needs. Parker o-rings Albuquerque are well-known for their unmatched dimensional consistency, outstanding performance, and material consistency. They are the ideal solution for your unique application and need.
If you want to customize your O-ring, you’ll be surprised at the variety of choices available. Parker offers different o-ring part numbering systems so you can quickly identify the o-ring that’s perfect for your application. These systems also let you choose the type of polymer, hardness, and operating environment required. The Parker O-Ring Division offers non-permanent markings, so you can use them on any market. And because they’re non-permanent, they won’t affect the O-ring’s performance.
Whether you need a replacement o-ring or an o-ring kit, the Parker O Ring Division is ready to help. With over 100 different products in their catalog, you’re sure to find the perfect o-ring for your application. In addition to o-rings, you can also buy custom piston seals and filter seals. If you have a specific need, you can also request a custom-made Parker o-ring for a cost-effective price.
PTFE o-rings
PTFE is a versatile material that has many advantages over other types of o-rings, including its low elasticity and resistance to a variety of chemicals. In addition, PTFE O-Rings are only capable of a very small amount of stretching during installation. Another important factor to consider is their tendency to flow cold, which means they deform permanently in cold temperatures. Aside from this, they may also degrade due to contact with metal.
If you require an o-ring that is particularly large or small, you may need to specify the type of material used.
The N0674 O-ring from Parker is a 70-durometer general-purpose nitrile. This material has unsaturated carbon-carbon bonds, which make it resistant to sunlight, ozone, and weathering. Its low friction characteristics make it an excellent choice for use in various dynamic sealing applications. In addition to reducing the risk of downtime, Resilon 4300 O-rings eliminate the need for back-ups.
