- This set includes 5 sizes of silicone hole plugs, designed to seal round holes, prevent water, dust, or debris from entering gaps in pipes, containers, or equipment. As rubber plugs, they offer a flexible sealing solution—compress slightly to fit their target holes, creating a tight barrier without damaging the surrounding surface, making them versatile for various sealing needs.
- The 5 sizes cover specific hole ranges: 11mm plugs fit 10.4-10.7mm holes, 15mm for 14.4-14.7mm, 18.5mm for 17.9-18.2mm, 19.5mm for 18.9-19.2mm, and 21mm for 20.5-20.7mm; all are made of soft, waterproof silicone. As rubber plugs for round holes, they conform to the shape of round holes, ensuring a snug fit that stays in place even with minor vibrations or temperature changes.
- These plugs feature a waterproof design that blocks liquid penetration, making them suitable for wet areas like sinks, bathtubs, or outdoor equipment. As silicone bottle stopper, they also work for sealing open bottle necks (like unused chemical bottles or beverage containers), preventing spills or contamination when stored upright.
- Ideal for homeowners (sealing gaps in bathroom fixtures, kitchen appliances), workshop users (protecting tool holes from dust), or plumbers (temporarily sealing pipe ends during repairs). As rubber bottle stoppers, a handy tip: measure your hole or bottle neck diameter first to match the correct plug size—for slightly larger gaps, soak the plug in warm water for 10 seconds to soften it, making it easier to stretch and fit.
- As silicone plugs for round holes, note that these plugs are not designed for high-pressure applications (avoid using on pipes with water pressure over 50 PSI) as they may dislodge. Also, keep them away from sharp edges when installing, as cuts to the silicone can reduce their waterproofing ability and reusability.
