uxcell Silicone Hole Plug for 145 mm Openings, Black Waterproof T-Shape Stopper

For a 145 mm opening that needs a waterproof seal, this black uxcell silicone hole plug offers a simple press-in solution. Its flexible T-shaped profile is designed to sit securely on smooth surfaces, helping close openings in applications such as a washbasin, bathtub, bottle or pipe end.

The silicone construction is soft and flexible, while the plug is designed to resist wear and help keep liquid and gas from draining out and dust from entering. It’s a practical way to cover an unused opening instead of leaving it exposed.

Why it’s worth it

The fit is specified for a 145 mm hole, so the opening size is the key detail to match when choosing this stopper. The listed inner diameter is 146.5 mm, the outer diameter is 155 mm, and the plug height is 18 mm, with a 23 mm overall height and a 5 mm bottom thickness. These measurements help you compare the plug with the opening and the space around it before installation.

Its T-shape is designed to conform to smooth surfaces and stay in place, while the silicone forms a waterproof, dustproof seal. That makes it useful for closing a washbasin or bathtub opening, sealing a bottle or tube, or covering an unused hole in furniture. Where the alternative is to leave an opening exposed, a correctly sized stopper gives you a straightforward way to close it without tools.

Key takeaways

This is a single black silicone plug for a 145 mm hole. The material is flexible and wear-resistant, and is designed not to crack, shrink, harden or break easily. For day-to-day use, that combination makes the plug suitable for applications where a firm seal and a flexible fit are both useful.

The stated applications include washbasin hole plugs, waterproof and sealing plugs, pipe plugs, bottle plugs and test-tube plugs. It can also cover unused holes. The intended fit and opening shape matter: compare the 145 mm fit-hole diameter with your opening before use, rather than relying only on the product’s outer dimensions. A solid pick if you need a silicone stopper for an opening that matches this size.

How to use it

Choose the plug size to match the hole, then press the stopper into the opening by hand, no tools are required. The T-shaped design sits against the surface to form the seal. For a sink or bathtub opening, seat it evenly so it covers the hole, for a bottle or tube, use it where the opening matches the specified fit. Its black finish also gives an unused opening a neat, covered appearance.

Final verdict

This uxcell stopper is suited to buyers who need a straightforward silicone closure for a 145 mm opening. Its flexible material, T-shaped profile and waterproof, dustproof sealing make it useful across listed household and container applications, from a basin opening to a bottle or pipe end. Match the hole to the stated fit size, then press the plug into place for a simple way to seal or cover it.
