What is an O-ring NBR - 70 Shore A - FDA - NSF61?

An O-ring NBR - 70 Shore A - FDA - NSF61 is a type of seal made from nitrile rubber (NBR) with a hardness of 70 Shore A. These O-rings are designed to meet the stringent requirements of both the FDA (Food and Drug Administration) and NSF61 (National Sanitation Foundation). The FDA certification indicates that the material is safe for use in applications that come into contact with food, while the NSF61 certification indicates that it is suitable for use in drinking water systems.

These O-rings therefore combine excellent mechanical properties with compliance with important safety and health standards, making them ideal for various industries such as the food industry and water treatment.

What does an FDA certificate mean?

An FDA certificate is issued by the Food and Drug Administration in the United States and indicates that a product meets strict safety standards for use in applications that come into contact with food. This means that the materials used in the production of the O-ring do not release harmful substances that could affect the quality of food or consumer health.

For an O-ring NBR - 70 Shore A - FDA - NSF61, this means that the material has been carefully tested and approved for use in food processing equipment, packaging machines, and other applications where food safety is crucial.

What does an NSF61 certificate mean?

The NSF61 certificate is issued by the National Sanitation Foundation and indicates that a product is suitable for use in drinking water systems. This means that the materials used do not release harmful substances that could affect the quality of drinking water.

For an O-ring NBR - 70 Shore A - FDA - NSF61, this means that the material has been extensively tested for its chemical properties and durability in aqueous environments. This certification is essential for applications in water treatment systems, pipelines, and other infrastructure where drinking water flows, as it ensures the safety and purity of the water.

Properties of NBR O-rings - 70 Shore A - FDA- NSF61

NBR (nitrile rubber) O-rings with a hardness of 70 Shore A have several properties that make them suitable for a wide range of applications. First, they have excellent mechanical properties, such as high tensile strength and good wear resistance, which ensures a long-lasting and reliable seal. Additionally, NBR O-rings - 70 Shore A - FDA - NSF61 offer good resistance to oils, fats, fuels, and many other chemicals, making them ideal for use in industrial environments.

The hardness of 70 Shore A means that an O-ring NBR - 70 Shore A - FDA - NSF61 is firm enough to provide a good seal, but also flexible enough to be easily installed and adapted to different surfaces. Moreover, these NBR O-rings - 70 Shore A - FDA - NSF61 meet both FDA and NSF61 standards, underscoring their suitability for food contact and drinking water applications.

The advantages of an O-ring NBR - 70 Shore A - FDA - NSF61

One of the biggest advantages of using an O-ring NBR - 70 Shore A - FDA - NSF61 is versatility. By meeting both FDA and NSF61 standards, these O-rings can be used in a wide range of applications, from food processing to drinking water treatment. Their excellent chemical resistance means they are resistant to many types of oils and chemicals, enhancing their lifespan and reliability.

The hardness of 70 Shore A offers an ideal balance between flexibility and firmness, ensuring a good seal without wearing out too quickly. Additionally, the fact that NBR O-rings - 70 Shore A - FDA - NSF61 are approved for food and water contact is an important reassurance for companies involved in the production and handling of consumer products.

Applications of an NBR 70 O-ring with FDA and NSF61

The applications of an O-ring NBR - 70 Shore A - FDA - NSF61 are diverse and extensive. In the food industry, these O-rings are used in machines and equipment that come into direct contact with food, such as mixers, packaging machines, and conveyor belts. Their FDA certification ensures they are safe for use in environments where hygiene and food safety are paramount.

In water treatment, an O-ring NBR - 70 Shore A - FDA - NSF61 is used in drinking water systems, water filters, and other infrastructure where the quality and purity of the water are essential. The NSF61 certification guarantees that the materials do not release harmful substances into the water. Moreover, they are also used in the automotive and aerospace industries due to their excellent oil resistance and mechanical properties.

The disadvantages of an NBR O-ring in 70 Shore A with FDA and NSF61

Although an O-ring NBR - 70 Shore A - FDA - NSF61 offers many advantages, there are also some drawbacks to consider. First, NBR materials have limited resistance to ozone, sunlight, and weathering, meaning they are less suitable for outdoor use or applications where they are exposed to these elements for extended periods.

Additionally, they may perform less well in extremely high temperatures, making an O-ring NBR - 70 Shore A - FDA - NSF61 not always suitable for applications where heat resistance is crucial. Finally, the cost of these certified O-rings can be higher than non-certified alternatives, which may be a consideration for companies with a limited budget.
