FAQs About White Silicone Hole Seal Plugs ❓
How do I choose the right size silicone hole plug?
Measure the inner diameter of your hole/tube (not outer diameter) and select a plug size slightly larger (0.5~1mm) for a tight seal. For example, a 5mm inner diameter hole works best with a 5.5mm plug—silicone’s elasticity will compress to fit.
When should I use a solid vs. hollow silicone plug?
Use solid plugs for full sealing (e.g., unused pipe ends, dustproofing machinery). Use hollow plugs if you need partial access (e.g., threading wires through a hole while blocking dust/water).
Can these silicone plugs be used with chemicals or acidic solutions?
Yes! They’re acid/alkali-resistant—safe for use with most common chemicals, cleaning solutions, or industrial fluids (avoid prolonged contact with strong solvents like acetone).
Are the plugs reusable, and how do I remove them?
Absolutely! Gently pull or pry the plug out (use tweezers for small sizes)—silicone retains its shape for repeated use. Clean with soap and water between uses.
