Rubber Stopper Sizes
In order to keep up with the demand of rubber stoppers for every application, we have started making rubber corks in every possible size. We also take the extra mile of giving custom rubber stopper sizes options. It means that our experts will comply with your changes in design, size, material, and model of the rubber stoppers. All our rubber stopper solutions are made from various types of durable and flexible rubber, which lasts longer, and is sturdy. We manufacture rubber corks from size 0 to size 25.
The vessel examples previously listed for rubber stopper sizes are grouped below by stopper designation. They help identify the intended application, but vessel capacity and outside dimensions do not establish the neck fit.
- Size 0, solid: the listed example is a 12 x 100 mm test tube.
- Size 1: examples include a 15 x 150 mm test tube, pear-shaped glass flasks of 100 ml or 50 ml, and a 25 ml round-bottom glass flask.
- Size 3, one hole: the test-tube examples are 18 x 180, 18 x 150, and a 20 x 200 mm glass screw-cap tube. Flask examples include a 50 ml round-base boiling flask; round-bottom glass flasks of 50 ml and 100 ml; and flat-bottom glass flasks in the same two capacities.
For the actual selection, compare the stopper’s tapered body with the measured opening and intended seating depth. A size designation from a different range may describe a different profile.
The size 13 solid hole rubber stopper can be used for 500 ml narrow mouth Erlenmeyer flask, 1000 ml narrow mouth Erlenmeyer flask, 1000 ml round base boiling flask, and 1000 ml vacuum filtering flask. We have versatile rubber stoppers in several sizes, including size 15 solid hole cork, size 15 one hole cork, size 15 two-hole cork, and size 16 solid hole rubber stopper. In addition to that, you can find various rubber stopper solutions for the narrow mouth and wide mouth tools as well. Our technical team is also known for the quick response and decent customer service, which is why it is best to get in touch with them for any queries related to the rubber stopper sizes.
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.
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.

Discuss Your RequirementsProduct specifications
- Product form
- Removable closure fitted inside an opening
- Application focus
- Erlenmeyer flasks and laboratory flasks. Size the part against the selected assembly.
- Dimensions to confirm
- Opening diameter, closure profile, insertion depth and exposed grip. Match these to Erlenmeyer flasks and laboratory flasks.
- Size selection
- Choose the drawing or chart row by its functional dimensions and units; verify mating-part tolerances before ordering.
- Profiles discussed
- Round profiles and tapered sections. Select the profile that matches the mating part and dimension that section explicitly.
- Seating check
- Check the sealing contact around the opening and the force needed for insertion and removal.
