It performs outstandingly in typical mechanical environments such as engines, hydraulic systems, and pipeline connections.
How do protrusions and indentations improve the sealing performance of a rubber O-ring?
The protrusions on the O-ring create close contact with the sealing surface, preventing medium leakage even under high pressure, high vacuum, or in systems prone to vibration and displacement.
What is the purpose of the auxiliary lubrication feature?
The indentations store lubricating medium, which provides continuous lubrication during relative motion. This minimizes wear, lowers the friction coefficient, and ensures smooth piston movement in hydraulic systems.
Can these O-rings reduce mechanical vibrations?
Yes. The unique structure of protrusions and indentations acts as a buffer that absorbs mechanical impact and vibrations, promoting system stability in engines and other vibrating equipment.
What are the temperature limits of these O-rings?
The temperature resistance depends on the material: Ethylene propylene diene monomer (EPDM) O-rings operate between -50°C and 150°C, while silicone rubber O-rings can withstand temperatures from -60°C to 250°C.
Why are these O-rings suitable for the automotive and aerospace industries?
They offer exceptional sealing, anti-fatigue, and vibration-damping capabilities. This makes them ideal for high-vibration, high-displacement environments like automotive engines, braking systems, aircraft fuel lines, and landing gears.
