Solid Rubber Stopper
Solid Rubber Stoppers are used to close or seal test tubes and are made from an excellent quality rubber with low sulphur content. They work with glass or plastic test tubes as well as Erlenmeyer flasks.
Solid rubber stoppers come in a convenient pack and are suitable for use in the science classroom or laboratory. When dealing with glassware, these stoppers are a must-have in the lab. They are chemically resistant, making them even more durable. The abrasion resistance of these solid rubber stoppers is excellent.
They’re tapered to match a variety of hole diameters and have increased resilience. It has a lot of versatility and can withstand a lot of chemicals in a lab environment.
Also, it’s incompatible with petroleum oils and hydrocarbon solvents.
A range of solid rubber stoppers/bungs are suitable for closing test tubes and flasks. Test tubes and flasks can leak, and solid rubber stoppers are the perfect solution for this. When we use solid rubber stoppers to close test tubes and flasks, it is better for all, including medical students and physicians.
The solid rubber stopper is intended to keep oxygen from interfering with the fermentation process. Slide it into the mouth of any carboy or fermenter, and the snug fit will seal the container. To get the best match, calculate the mouth’s diameter to your carboy or fermenter and equate it to the diameter of the stopper. It seals the mouth of your carboy or fermenter and prevents air from getting in.For beer and wine equipment, solid rubber stoppers are often used. These stoppers are also helpful for several other projects around the house. The sizes of these stoppers range from size 000 to size 15. It has a more robust seal than different types of stoppers, and they are durable.

Stopper & Plug Size Catalog
Compare four stopper profiles and check the selected part dimensions against your opening and available depth. Each profile has its own drawing and dimension meanings.
Custom colors are available to your Pantone color code. Include the code in your inquiry.
RST T-Shaped Plugs
Match stem diameter A, flange diameter B, stem length C and flange thickness D. E refers to the underside recess; use the selected row and approved drawing to confirm the actual profile.
RSA Tapered Corks
Compare large-end diameter A, small-end diameter B and Height, in mm. The mating bore and required seating depth determine where the taper contacts the opening.
RSB Undercut Plugs
Compare neck diameter A, flange diameter B, flange-to-lip distance C and flange thickness D. Check panel thickness and rear clearance. E refers to the underside recess.
RSD T-Shaped Stoppers
Compare stem diameter A, flange diameter B, stem length C and head thickness D, in mm. Check the seating surface and available depth as well as the hole diameter.
