How to Choose the Perfect AS568 O Ring?
O rings are essential components in many applications such as sealing, fluid transfer, and vibration absorption. There are a variety of O rings available in the market, but choosing the right one for your application can be challenging because of the different sizes, materials, and properties. In this article, we will guide you on how to choose the perfect AS568 O ring for your specific application.
Identify your Application Requirements.
Before selecting an AS568 O ring, you need to understand the demands of the application. The following are some of the questions that can guide you in identifying your application requirements:
- What are the pressure and temperature conditions of the application?
- What fluid(s) will the O ring be exposed to?
- What are the size and tolerance requirements of the application?
- What type of motion does the O ring need to withstand?
Answering these questions will help you determine the ideal material, size, and properties of the AS568 O ring that you need for your application.
Select the Right Material.
The material selection is crucial since it determines the compatibility, physical properties, and chemical resistance of the O ring. The following are some of the materials you can choose from:
- Nitrile (NBR): Nitrile is the most common choice because it has excellent oil and abrasion resistance. It is ideal for applications with petroleum-based fluids.
- Viton (FKM): Viton is suitable for high-temperature applications and exposure to chemicals such as acids and oils.
- Silicone (VMQ): Silicone is ideal for applications that require high flexibility and low-temperature resistance.
- EPDM: EPDM is suitable for applications with exposure to hot water or steam.
Evaluate the Properties.
The properties of the O ring should match the requirements of your application. Here are some of the essential O ring properties to evaluate:
- Durometer: Durometer is the measure of an O ring's hardness. It is crucial to select the right durometer for the application to ensure a proper seal.
- Tensile Strength: Tensile strength is the maximum amount of force an O ring can withstand without breaking. Applications with high-pressure require O rings with high tensile strength.
- Compression Set: Compression set is the ability of the O ring to return to its original shape after being compressed. A low compression set is ideal for applications that require repeated compression.
Choose the Right Size.
The size of the O ring should match the required shaft size, housing, and groove. Using the wrong size can cause the O ring to fail, thus compromising the application. The AS568 O ring size chart provides a variety of sizes to choose from.
Conclusion.
Selecting the right AS568 O ring for your application is crucial for achieving a proper seal, eliminating leakage, and improving equipment efficiency. By identifying the requirements, selecting the right material, evaluating the properties, and choosing the right size, you can ensure that you have chosen the perfect O ring for your application.
