Tips to Buy Parker O-Rings

When you buy Parker O-Rings, there are several important factors you should keep in mind. Here are a few of these: size, material, and compatibility with fluids. Consider these factors before you go out and buy a new set. If you’re having trouble deciding on which o-ring to purchase, consider these tips! Using these tips can make the entire process a lot simpler.

Factors to consider when buying Parker O-Rings

You need to find out the exact size of a Parker o-ring. Fortunately, the company has a handy guide to help you choose the correct size. The guide also includes information on the material and hardness of o-rings. Parker O-rings can be found on their catalog website or at their headquarters. To make your decision easier, here are some factors to consider when buying Parker o-rings.

The material and compound used to make these parts is based on the specification for that part. For example, a Parker O-ring made of the 2-211 series is 8-211, N 300-90. A Parker O-ring made of Parbak(r) material has a hard rubber compound that enables it to stretch into place and resist pressure and abrasion. A Parbak is also used to enhance the sealing properties of an O-ring.

The price of a Parker O-ring is an important consideration when purchasing a product. Price is only one of several factors to consider when buying Parker O-rings. Make sure to buy from a reputable source, as low prices may lead to poor quality. Parker O-rings are available in kits of four or more sizes, which will ensure that you have what you need. Make sure that the O-ring you purchase is compatible with the materials used for the job.

The type of material is also important. Most general-purpose O-rings are made of nitrile, a polymer that offers excellent chemical resistance and a low compression set. Some are also resistant to sunlight and ozone. But don’t use a polymer made of silicone, as it will not last as long as a nitrile O-ring. And if you are using O-rings in high-temperature applications, a silicone one will be the best choice.

Extrusion limits are another important factor to consider when buying a Parker O-ring. Extrusion limits are based on 100,000-pressure cycles. At 60/min, a cylinder expands by about 5%. And a reasonable safety factor accounts for cylinder expansion due to pressure. Also, make sure the o-rings you purchase have high elongation to fit into the space between the grooves.

Materials

If you’re looking for a high-quality o-ring, then you’re in the right place. Many world-class manufacturers of industrial parts produce Parker O-Rings, which are made of a unique organic polymer called polyurethane. This material is formed by reacting a polyol with either diisocyanate or polymeric isocyanate. It provides superior strength, tear resistance, and permeation resistance.

There are many different types of materials for O-rings, each offering unique features and benefits. Some are compatible with various oil types, while others may deteriorate under certain operating conditions. Choosing the right O-ring material depends on your specific requirements, including the application temperature, chemical compatibility, and abrasion resistance. Consider your budget, the amount of heat you’re willing to endure, and the overall performance of your parts.

One type of polymer is neoprene, which is an excellent material for sealing parts that are subjected to high temperatures. Its resistance to heat, oil, and fuel is excellent. It is also resistant to abrasion and flex cracking. Fluorocarbon O-rings are also popular, and are often called viton. These types of O-rings combine excellent chemical and heat resistance with a relatively low cost.

Critical medical seals have to be made with cleaner ingredients. This is why they must be made with materials certified to the National Sanitation Foundation (NSF 51) Standard. This means that they must pass stringent extraction tests to meet the strict requirements of the FDA. The United States Department of Agriculture (USDA) also has standards. These stricter requirements have led to additional requirements for seal manufacturers for the food and beverage industry.

O-rings are available in a variety of sizes. They can be as small as one-half inch or as large as one-inch. O-rings are generally made of rubber and elastomer, but can also be made from PTFE or other thermoplastic materials. Whatever your requirements, we can help you find the right O-ring for your needs. When you need a high-quality o-ring, choose an experienced and dependable supplier.

Sizes

If you’re not sure which size of Parker o-rings you need, you can refer to the chart that lists the various materials and hardness levels. The chart can be helpful to customers, as it can help them choose the best fit and material for their specific application. The chart also lists the different types of materials and their appropriate hardness levels. If you’re not sure which size you need, try using the o-ring selector on the Parker website.

To measure the proper size, you can use the Parker O-Ring Size Gauge. The device comes with a uniquely-marked plastic cone and a special base. The tape is separate from the cone and is used to measure the o-ring size to the nearest standard Parker Seal 2-dash size. You should note, however, that the chart’s measurements are nominal and not true metric dimensions.

There are several materials that are NORSOK-compliant. The NORSOK-certified Parker O-Ring material is designed to outperform standard materials. To find out more about the material, search under “Potentially Reliable Parker O-Rings” or “PARK” in the product’s compound number. The datasheets for these materials can be found on the website of southwest supply by the compound number.

The O-Ring Selector allows you to choose the material and size for your application, ensuring you receive the optimal performance from your seal. The calculator covers both imperial and metric standards and incorporates a wide range of sealing materials. The calculations take into account the operating temperatures, fluids, and other variables relevant to your specific sealing application. It also takes into account the required approvals and conformance.

Parker O-Rings are also available in Nitrile Buna-N (NBR) compound. These elastomer compounds are common in enclosed environments, and their natural resiliency is vital to the seal’s sealing process. For maximum sealing performance, however, you should always use the right material for the specific application. A high-quality O-ring will last for years, even if it goes through a lot of wear and tear.

Compatibility with fluids

For more information on the compatibility of Parker O-Rings with fluid types, check out the company’s Compatibility of Parker O-Ring with Fluids Handbook. This handy guide highlights over 1,800 different chemicals and their compatibility ratings against common o-ring materials. The handbook lists chemicals alphabetically, with their respective materials in the column header. It also includes some general information on what the chemical is.

Many Quantachrome instruments feature O-rings that are compatible with fluids and gases. While these rings are made of the same basic polymeric seal materials, they differ in their compatibility with various gases and vapors. The table below lists the compounds that each Quantachrome O-Ring is compatible with, along with their respective compatibility ratings. For more detailed information, read the corresponding section of the manual.

As the O-Ring material used in Validyne transducers is compatible with oil, water, and most gases, Buna-N is a good option. While Teflon is compatible with a variety of fluids, it lacks elasticity and can negatively impact transducer performance. Furthermore, it can cause clamping force on the sensing diaphragm, reducing accuracy. It is therefore recommended that you purchase an O-Ring that has some elasticity.
