From high-speed seals to precision mechanical seals, Parker has a product to meet your needs. Here’s a brief overview of Parker’s O-Rings. So, go now and read on to find out more. Listed below are the different types of O-Rings. You can choose from polyurethane, Nitrile, butadiene, and acrylonitrile.
Polyurethane
To find the perfect O-Ring for your application, consider the wide range of materials and compounds offered by the Parker O-Ring Division. You can access the full listing of Parker’s O-Rings by compound number, or search for specific materials by name. The company also emphasizes Controlled Batch Identification and quality assurance programs. Parker O-Rings can withstand high temperatures and aggressive chemistries.
A polymer such as nitrile contains ethyl and acrylates copolymers. They resist oxidation and corrosion caused by petroleum-based fluids. Their size is measured by the cross-section. The most common-inch size is SAE AS568C. The compound’s data sheet provides additional information on the O-ring size and composition. It’s recommended that you contact a Parker representative if you’re unsure of which material to use for your application.
Polyurethane gaskets and O-rings offer excellent performance in a variety of demanding applications. The materials’ outstanding abrasion resistance, high elasticity, and rebound to make them ideal for applications that require a high degree of resistance to impact, heat, and chemical reactions. Polyurethane is not suitable for all applications, but common uses include hydraulics, pneumatics, automotive, and hydrostatic testing.
Polyurethane O-Rings from Parker Seals provide excellent sealing and heat resistance. These O-Rings are available in standard sizes, as well as customized O-Rings. In addition, Resilon polyurethane is a proprietary formulation. These materials provide excellent flexibility and high strength, which reduce downtime and repair costs. The Resilon O-Ring is available in a range of standard sizes, from small to large, and can be customized to meet the needs of customers.
The materials used in the manufacturing of critical medical seals are required to be more durable and clean. This includes ingredients approved by the U.S. Food and Drug Administration (FDA). U.S. Pharmacopeia Class VI has strict requirements regarding system toxicity, intracutaneously toxicity, and leachates. This is another important requirement for manufacturers of medical seals, which is why Parker has developed polyurethane compound formulations that meet the strict requirements for these applications.
Nitrile
A wide range of applications require a variety of sealants, and Nitrile Parker O-Rings is among the most popular options. These elastomers, also known as Buna-N, are a copolymer of butadiene and acrylonitrile. They are highly durable and have excellent sealing capabilities. Moreover, Nitrile Parker O-Rings are available in high-visibility versions, which provide improved visibility.
Nitrile Parker O-Rings is NORSOK-compliant, and their hardness ratings range from 70 to 90. They offer a balanced combination of strength and resistance but are not suitable for high-temperature applications or exposure to ozone. The exact formulation of nitrile depends on the polymer’s composition. Some types of nitrile are hydrogenated for increased strength at high temperatures.
These O-Rings are a great choice for demanding applications requiring increased strength, toughness, and durability. Parker seals also offer excellent permeation and tear resistance. You can browse their full catalog to find the ideal O-Ring for your application. You can also contact an application engineer to get expert advice on the best O-Ring for your application. If you’re in the market for an O-ring, contact Sealing Devices today.
Nitrile Parker O-Rings are available in a range of nitrile compounds, which differ in content from 18% to 50%. Depending on your application, Nitrile Parker O-Rings are available in various durometers.
The American National Standards Institute recognizes NSF International, which develops qualification criteria for potable water components and delivery systems. You can read more about NSF-certified materials on the company’s website.
Nitrile-butadiene
If you are looking for a high-quality O-ring, look no further than the Parker O-Rings line. Nitrile-butadiene is a synthetic rubber that combines the strength of nitrile with the chemical resistance of polymeric isocyanates.
This O-ring is resistant to high temperatures but has limited ozone and UV resistance. It also has less heat resistance and can be brittle when exposed to water. The nitrile-butadiene Parker O-Rings line is available in different durometers and materials. You can choose from 70 and 90-durometer O-rings to meet your needs.
Nitrile-butadiene (NBR) O-rings are made from the same rubber compound as Buna-N. Southwest supply offer excellent sealing properties at a low price. They are also highly durable and are great for applications where the O-ring must be visible. The process for making them is simple, but manufacturers take into account lubrication requirements and application environment. These factors affect the choice of O-ring material.
Nitrile-acrylonitrile
The material is crucial in the manufacturing process. The properties of various O-ring materials differ in price, dimensional control, and chemical compatibility. The choice of material is based on the specific application. For low-priced O-Rings, nylon is a great option and offers excellent dimensional control. For a higher-quality material, Parker uses the Kalrez elastomers, which are FDA-compliant and offer outstanding performance properties.
Parker offers a wide variety of chemically-inert compounds to meet the demanding needs of industrial applications. They are manufactured to meet the strictest industry standards and are available in a Shore A range of forty to 95. A Parker Authorized Distributor Sealing Devices offers the right product for the application. The company’s goal is to deliver quality products with unmatched service.
FDA-certified materials are required for critical medical seals. These compounds must pass extensive toxicity tests, including system and intracutaneously, as well as strict leachates tests. Food-service equipment also requires stringent materials. Parker materials meet these standards. These materials are a great choice for applications that require abrasion resistance and high-quality food-contact. The FDA approval is a good indicator of quality.
Despite the fact that nitrile is made from a synthetic rubber, its chemical resistance is exceptional. While other materials react with hydrocarbon fuels and oils, nitrile stays unaffected by diluted acids. This makes nitrile/Buna-N O-rings an excellent choice for fueling systems in automotive and marine engines. They also have excellent tensile strength, which makes them versatile for many industries.
