상품 특징

• Premium Solid Rubber Construction for Long-Lasting Use: Made from high‑quality, flexible rubber, these 8 solid rubber stopper bungs resist cracking, tearing, and chemical corrosion. Unlike brittle plastic or cork, our durable rubber tapered plug maintains a tight seal even after repeated use. Ideal for lab apparatus, home flask, or test tube applications where reliability matters. The resilient material ensures easy insertion and removal without deforming.
• Smart Single‑Hole Design for Versatile Functionality: Each rubber stopper with hole allows secure passage of tubing, thermometers, or wires while preventing leaks. Whether you need a drilled rubber stopper for aeration setups or a fountain plug with cord slit for water features, this design fits. Use as a test tube stopper with hole, or as a replacement plug for carboys, jugs, and fermentation vessels. One hole, endless possibilities.
• Tapered Shape Fits Multiple Sizes – No Guesswork: The conical profile of our rubber tapered plug works like a universal stopper. Simply press until snug – it seals bottle necks, flask openings, and sink drains from ½″ to 1″ diameter. No need to buy separate sizes for different containers. Perfect as a pipe stopper plug, drain plug, or water table plug replacement. Easy to trim if needed, but the flexibility already adapts to irregular openings.
• 8‑Piece Set – Always Have the Right Stopper Ready: Stop searching for a single drilled rubber stopper when you need it. This 8‑pack gives you spares for multiple projects: home brewing, aquarium filters, essential oil distillation, or even as a slobber stopper for pet bowls. Each piece is washable and reusable. Compare to buying individual fountain plugs – you save money and time. Great for teachers, hobbyists, and lab workers.
• Easy to Insert, Remove & Clean – No Tools Required: Thanks to the flexible yet strong rubber, you can push in or pull out these rubber stoppers bungs by hand. The non‑stick surface rinses clean under water. Use for bleeding stopper plug applications, or as a spherical rubber stopper for flask sealing. No more struggling with stuck corks or damaged glassware. Just a smooth, snug fit every time – even after autoclaving (up to 250°F).
