MECCANIXITY Silicone Rubber Solid Plug Soft Flexible Stoppers for 12-12.5mm Hole White 24 Pieces

Description

Product Overview

The MECCANIXITY Silicone Rubber Solid Plug is engineered to deliver a dependable seal across a wide range of applications, from scientific laboratory glassware to everyday kitchen containers. Crafted from high‑grade silicone rubber, each plug combines softness with resilience, allowing it to conform snugly to holes ranging from 12 mm to 12.5 mm while maintaining a tight, leak‑free barrier. The material exhibits excellent chemical resistance, standing up to acids, bases, and solvents commonly encountered in lab environments. Additionally, the silicone can tolerate short‑term exposure to temperatures as high as 600 °F (315 °C), making it suitable for processes that involve heating or sterilization. The T‑shaped design provides a larger top diameter (approximately 16 mm) for easy handling, while the lower profile (about 12.8 mm in height) fits discreetly into standard bottle necks and flask openings. Each package contains 24 white plugs, offering a cost‑effective solution for bulk users and ensuring you always have the right size on hand.

Usage

These silicone plugs excel in laboratory settings where a secure, chemical‑resistant seal is essential. They are ideal for sealing reaction vessels, storage bottles, and distillation apparatuses, preventing evaporation and contamination. In the kitchen, the same flexibility and heat tolerance make them perfect for sealing spice jars, oil bottles, and even homemade preserves, allowing you to reuse containers without worrying about leaks or degradation. The plugs are also valuable in educational environments, where students frequently need to close test tubes and beakers during experiments. Because the plugs require no tools for insertion or removal, they save time and reduce the risk of breakage associated with metal caps or screw‑type closures. Their soft texture ensures a gentle grip, protecting delicate glassware while still providing a firm seal.
