Description
Silicone stopper, 19 x 24 x 25 mm, transparent, is a clear elastomeric plug for laboratory and process closures. Delivered as one piece per pack, it is made from silicone that is food-grade according to FDA and BfR requirements. Shore hardness is approximately 50°, and the material remains serviceable from −60 °C to +220 °C, with short-term exposure up to 260 °C. Dimensional tolerances follow DIN 7715 Part 2 M4 for consistent fit. Typical application areas include the laboratory, wine industry, pipe technology and electroplating, where a transparent, chemically robust silicone seal is advantageous. This stopper from manufacturer Dinkelberg can be supplied with optional through-bores or blind holes for tubing or probes when required. The transparent body aids visual checks of contents or inserted lines. Suitable for flasks, bottles, tubes and related fittings that need a high-temperature, food-compatible silicone closure in a compact 19 x 24 x 25 mm format. Country of origin is Germany.

Questions about Silicone plug, 19 x 24 x 25 mm, transparent, 1 pc/pak Quality: Silicone,
What is this article?
Silicone plug, 19 x 24 x 25 mm, transparent, 1 pc/pak Quality: Silicone, is the article on this page. Luminix Health distributes Dinkelberg for laboratory use. It sits in Bouchons en verre à rodage, inside Bouchons, capuchons & fermetures, in Matériel de laboratoire.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
