Sourcing Industrial Equipment

Leakages are a significant concern for people in the manufacturing and fabrication industries. Typically, a leak compromises a part's functionality and increases its rate of tear. O-rings refer to elastic loops used to prevent liquid and gas leakages. Below is an extensive guide to help you purchase O-rings for your desired application. 

Determine The Size And Type Of O-Ring 

There are two ways to examine the O-ring size: inner diameter and cross-section. The inner diameter helps determine whether the ring will fit where you intend to install it. On the other hand, the cross-section affects the O-ring's ability to seal the affected area. You will find two types of O-rings on sale. A static O-ring suits applications without any movement, such as faucets. Conversely, dynamic O-rings seal surfaces where movement exists between the two surfaces. For instance, you will find them in pistons, pumps and hydraulic and pneumatic systems. 

Establish The Features Of The Desired O-Ring

The O-ring's material significantly affects its application. For instance, nitrile butadiene rubber (NBR) O-rings are suitable when working with petroleum or hydraulic fluids. On the other hand, you should consider ethylene-propylene (EPDM) O-rings when working with steam, water and oxygenated and alkaline liquids. Neoprene (CR) O-rings seal in refrigerants, mild acids, petroleum oils and lubricants. 

You must also assess essential qualities such as the O-ring's temperature range. The general rule is to purchase O-rings with a higher temperature range than you need. This way, you are not worried that the O-ring will give in due to slight temperature deviations. When buying a dynamic seal, assess its operating speed and pressure to ensure the ring remains functional when the equipment operates at maximum capacity. 

Assess The O-Ring's Durability 

Examine the O-ring's durability. Most manufacturers will state the ring's durability if you do not exceed its operating specifications. However, you should conduct due diligence to establish the O-ring's build quality. For instance, you could assess mechanical blogs or forums to compare the performance of different brands on sale. It is a sure way to ensure you purchase high-quality products. 

Purchasing Tips

Most people opt to buy O-rings online. As a best practice, you should ensure the seller allows you to return the O-ring if it does not meet the required criteria. Furthermore, you might want to consider sellers who offer additional services such as installation and shipping.
