Rubber stopper hole
A rubber stopper hole may seem like an unnecessary accessory for these small but handy items, but it’s actually essential to a wide range of tubing applications. Without rubber stopper holes, an intense buildup of pressure would occur inside of the tube. That would, in turn, cause the pipe to explore or crack, which could cost you tons of money in the long run, especially if you’re using the stoppers for industrial purposes. These holes come in various sizes and diameters and are perfectly customizable. All you need to do is to check the tube specs carefully before ordering. Remember that you’ll deal with rubber, which is usually quite flexible depending on the mixture of materials used to manufacture the stoppers in question.
Other than that, rubber comes with specific advantages of its own, such as resistance to heat, dusting, and extreme pressure. All rubber stoppers are exceedingly sturdy, long-lasting and durable. Still, you should make sure to choose your supplier carefully, as, again, not all rubber stoppers are made out of the same “mixture” of rubber materials. Ask for samples before ordering, and consider making bulk purchases if you’re working on a large-scale project. In that way, you’ll be able to save yourself from wasting your time and money on incompatible items.
These items are used in a wide range of applications, including their commercial use as well as for industrial and scientific purposes. Whatever the case, getting specific tube specs and reading up on reviews and ratings online before making your purchase is of the utmost importance.
Lastly, consider seeking expert assistance if you’re uncertain which rubber stopper hole diameter suits your project the best. Most suppliers will help you by providing you with helpful advice and information about their products. If, even after that, you cannot find something that fits your needs, consider ordering custom-made rubber stoppers instead.
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.

Discuss Your RequirementsProduct specifications
- Product form
- Rubber stopper with a passage through its body.
- Opening and bore
- Specify the container-opening dimensions separately from the stopper bore diameter and its position.
- Inserted item
- Match the bore to the tube, probe or fitting and specify engagement without closing its passage.
- Venting function
- If the passage is intended to vent, define the required flow and pressure conditions; a hole alone does not establish a rated pressure-relief function.
- Fit validation
- Check the outer seal, retention and the bore interface together on the actual assembly.
