While O-rings have always been a widely used sealing solution, care must be taken to avoid some of the common pitfalls of choice. An incorrect O-ring is placed under pressure, and reasonable planning will eliminate the problem, and the choice of O-rings is no exception. The following six-step guide can help solve the sealing problem for each O-ring.

1, silicone products custom introduction O-ring sealing guide: determine the type of application of your work and O-ring;

2. Make sure the media is blocked;

3. Define the time, temperature, and pressure envelope of the application as applicable;

4. Determine the size of the O-ring based on the type of application (ie, face, radial, static, dynamic, etc.);

5. Check the engineering calculation manually or use the software program;

6. O-ring seal guide: test design, if possible.

Several PC-based O-ring selection packages can help engineers, regardless of the method of litigation, the above steps will prove to be reliable and complete. Let's take a closer look and look at each step.

Static or dynamic?
Sealed applications can be divided into two categories: static and dynamic. In reality, the vast majority of sealing applications are naturally pseudo-static or quasi-dynamic. Real static applications, in the absence of vibration, are very rare. In order to avoid problems at this point, the designer must be familiar with all aspects of the operating environment of the O-ring.

Customized silicone products introduce vibrational motion, ozone attack, high UV exposure, intermittent use, continuous use, etc., all examples of whether the application is static or dynamic radial radial decisions. Be sure to take the next step to gain an understanding of these seemingly low-key designs.
