Buna-N 70 Shore A Durometer NBR O-Rings, Size N3.00x042 (3mm x 42mm), Pack of 135

Description:

These Buna-N 70 Shore A Durometer NBR O-Rings are designed to provide reliable sealing performance in various industrial and automotive applications. The NBR (Nitrile Rubber) material offers excellent resistance to oil, fuel, coolant, and water, making it a popular choice for sealing systems in automotive engines, hydraulic systems, and industrial machinery.

The dimensions of these O-Rings are size N3.00x042, which translates to an inside diameter of 42mm (1.653 inches) and a cross-section width of 3mm (0.118 inches). The length of each O-Ring is determined by the application and can be customized upon request.

The durometer hardness of these O-Rings is 70 Shore A, which offers a good balance between flexibility and resistance to compression set. This hardness level makes them suitable for applications where there is a need for high compression load or where the temperature ranges from -20 C to 90 C (-4 F to 194 F).

This pack includes 135 individual O-Rings, ensuring that you have an ample supply for your sealing applications. The O-Rings are shipped in a protective bag to ensure their integrity during transportation.

These O-Rings are manufactured to meet the highest standards of quality and reliability. They are suitable for use in harsh environments and can handle the demands of heavy duty industrial and automotive applications.

In summary, these Buna-N 70 Shore A Durometer NBR O-Rings, size N3.00x042 (3mm x 42mm), offer excellent sealing performance in industrial and automotive applications where resistance to oil, fuel, coolant, and water is crucial. The pack of 135 ensures a sufficient supply, and the 70 Shore A durometer hardness offers the required flexibility and resistance to compression set.

An In-depth Analysis of Buying an NBR Buna-N O-Ring (3mm, 42mm, N3.00x042, 70 Shore A Durometer, Bag 135)

Introduction:

The NBR Buna-N O-Ring (N3.00x042, 3mm, 42mm, 70 Shore A Durometer, Bag 135) is a critical component in various industrial applications, including automotive, aerospace, and hydraulic systems. This analysis aims to provide you with valuable insights into the advantages and disadvantages of purchasing this specific type and size of O-Ring.

Pros:

1. High Durability: With a 70 Shore A Durometer rating, this O-Ring offers excellent resistance to abrasion, compression set, and tear. It is well-suited for high-pressure and high-temperature applications.

2. Chemical Resistance: NBR Buna-N O-Rings exhibit excellent resistance to various chemicals, making them suitable for use in environments where exposure to chemicals is unavoidable.

3. Wide Operating Temperature Range: This O-Ring can function effectively in a relatively broad temperature range, making it a versatile choice for various industrial applications.

4. Excellent Sealing Properties: NBR Buna-N O-Rings are renowned for their ability to provide a tight seal, ensuring efficient fluid containment and preventing leakages.

Cons:

1. Limited Flexibility at Low Temperatures: The O-Ring's performance can be adversely affected at low temperatures, resulting in decreased flexibility and potential sealing issues.

2. Swelling in High-Temperature Applications: Prolonged exposure to high temperatures can cause the O-Ring to swell, which may impact its sealing efficiency and overall functionality.

3. Potential for Compression Set: Although this O-Ring has a relatively high durometer rating, it is still susceptible to some degree of compression set over time, which can affect its sealing capacity.

Conclusion:

The NBR Buna-N O-Ring (N3.00x042, 3mm, 42mm, 70 Shore A Durometer, Bag 135) is a robust and versatile sealing solution that offers excellent chemical resistance, high durability, and a wide operating temperature range. However, it may not perform optimally at low temperatures or in applications with extreme temperature fluctuations. Ultimately, considering the specific requirements of your application and the potential impact of temperature variations on the O-Ring's performance will help you make an informed purchasing decision.

Recommendation:

If your application involves high-pressure, high-temperature conditions and exposure to chemicals, the NBR Buna-N O-Ring (N3.00x042, 3mm, 42mm, 70 Shore A Durometer, Bag 135) is an excellent choice. However, if low temperatures or temperature fluctuations are a concern, you may want to explore alternative O-Ring materials, such as Viton or PTFE, to ensure optimal performance in your application.
