In the petroleum industry, AS568 standard rubber O-rings are a crucial sealing component. They are widely used in various stages such as oil and gas extraction, pipeline transportation, and storage facilities to ensure equipment's sealing and safety.

AS568 O-rings typically offer excellent oil resistance, high-temperature resistance, and chemical corrosion resistance, making them ideal for the harsh working conditions in the petroleum industry. 

The primary function of O-rings is to provide effective sealing in both static and dynamic conditions through their elasticity and shape.

In summary, AS568 standard rubber O-rings play an irreplaceable role in the petroleum industry. With their resistance to high pressure, high temperature, and chemical corrosion, they ensure the safety and reliability of petroleum equipment.
