Functions, Roles and Advantages of Rubber Hole Plugs

Core Functions

1. Sealing & Barrier Protection
   Isolates liquids (water, oil, chemicals), dust, sand, debris and other external impurities from entering equipment cavities or pipelines, while preventing internal grease and liquid leakage.
2. Noise & Vibration Damping
   Leveraging rubber's elastic properties to absorb vibrations generated by equipment operation and reduce component collision noise; sealing holes minimizes air-borne noise for enhanced equipment quietness.
3. Insulation & Safety Guard
   Boasts excellent electrical insulation to isolate contact between metal holes and wires, avoiding short-circuit risks; prevents accidental contact with sharp edges or live parts inside equipment for safety protection.
4. Hole Shape Retention
   After being inserted into pre-drilled holes in metal or plastic sheets, it prevents hole deformation, wear or edge cracking caused by external pressure, thermal expansion and contraction.
