Rubber Stoppers With Hole
If you are in search of durable rubber stoppers with hole designs, then you have reached the place. We are an established rubber cork manufacturer with a valuable customer base across the world. Taking into account the rise in demand for these tools, we deliver solid rubber stoppers, one-hole rubber stoppers, and two-hole rubber stoppers. Our rubber cork products are pliable, sturdy, premium quality, affordable, and last for a longer duration. As an experienced manufacturer, we produce rubber stopper solutions for several types of test tubes, flasks, jars, and other equipment.
For rubber stoppers with holes, check the closure body and the passage arrangement separately. The original article gives three body examples: a size 1 one-hole part with a 15 mm top, 10 mm base and 26 mm height; size 3 in a single-passage layout, measuring 19 mm across the upper end, 14 mm at the lower end and 26 mm tall; and a size 13 two-hole version with upper and lower diameters of 40 mm and 33 mm, at a height of 25 mm.
The associated vessel examples are retained here as references. For size 1, they are a 25 ml round-bottom glass flask and pear-shaped glass flasks of 50 ml or 100 ml. For size 3, the list includes 18 x 180 and 18 x 150 test tubes, a 20 x 200 mm glass screw-cap test tube, and a 50 ml round-base boiling flask. It also names round-bottom and flat-bottom glass flasks, each in 50 ml and 100 ml capacities. The two-passage size 13 example is associated with a 500 ml narrow-mouth Erlenmeyer flask and a 1000 ml round-base boiling flask. Check the actual neck before adopting any of these pairings, and specify the passage size for the item that will run through it.
As the application of rubber stoppers is increasing, the need for new designs and unique sizes is expanding. As a solution, we have started offering custom options for rubber stoppers with hole solutions. Some of our high-end products also come with a specific warranty. You can know more about the rubber stoppers, their pricing, order placing, delivery options, payment choices, and other things by getting in touch with us.
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.
