Now I want to list some methods to clean our silicone seal ring.Proper cleaning of the mating surfaces is essential for achieving a good seal when installing silicone seal rings. Here are some methods for cleaning the surface:

Wiping with a clean cloth: The simplest method is to wipe the mating surfaces with a clean, dry cloth to remove any dust, debris, or loose particles. This method is best used for surfaces that are not heavily soiled or contaminated.

Solvent cleaning: For surfaces that are heavily soiled or contaminated with grease, oil, or other substances, solvent cleaning may be necessary. Use a suitable solvent such as isopropyl alcohol, acetone, or brake cleaner to clean the surfaces. Be sure to use appropriate personal protective equipment and follow all safety precautions and manufacturer’s instructions when using solvents.

Sandblasting or abrasive cleaning: For surfaces that have rust, corrosion, or another heavy build-up, abrasive cleaning may be necessary. This method involves using sandblasting equipment or abrasive pads to remove the build-up and expose a clean surface. Be sure to use appropriate safety equipment and follow all safety precautions and manufacturer’s instructions when using abrasive cleaning methods.

Ultrasonic cleaning: Ultrasonic cleaning is a method that uses high-frequency sound waves to create tiny bubbles that remove contaminants from the surface. This method is particularly effective for small or intricate parts that may be difficult to clean using other methods.

Mistake #4: Overstretching the Seal Ring

Overstretching a silicone seal ring can cause it to lose its shape and ability to create a seal. Here are some potential consequences of overstretched seal rings:

Leakage: The primary consequence of overstretched seal rings is the increased likelihood of leaks. The seal ring becomes less capable of maintaining a tight seal, leading to leaks.

Poor Performance: Overstretched seal rings can also cause the equipment to underperform or even malfunction in some cases. This can also lead to premature wear and damage to the equipment.

Equipment damage: Overstretched seal rings can cause damage to the equipment that they are intended to seal. This can be due to reduced performance, increased vibration, or other factors caused by the lack of proper sealing.
