The main functions of sealing plug board dustproof Rubber stoppers include:

1. Dust and Contaminant Protection: Effectively blocks dust, dirt, and pollutants from entering equipment or openings, keeping the interior clean.

2. Sealing and Waterproofing: Provides excellent sealing performance, preventing moisture, oil, or Other liquids from penetrating the equipment, thereby protecting electronic components or mechanical parts.

3. Shock Absorption and Vibration Reduction: The rubber material offers elasticity, reducing vibrations and impacts that could damage the equipment.

4. Insulation Protection: In electrical equipment, rubber stoppers act as an insulator, preventing short circuits or electric shock risks.

5. Filling and Fixation: Used to fill openings, making the equipment structure more complete and preventing foreign objects from entering or affecting normal operation.

These rubber stoppers are widely used in electronic devices, automobiles, mechanical manufacturing, and Medical Equipment.
