Hole Rubber Stopper

Custom Rubber Stopper with Hole

Hole rubber stoppers are molded rubber plugs designed with one or two precision holes to allow tubing, wiring, or fluid transfer while maintaining a secure seal. They are widely used in laboratory glassware, bottles, chemical containers, and industrial equipment where controlled airflow or liquid passage is required.

We manufacture custom hole rubber stoppers in a wide range of rubber materials, sizes, and hardness levels. Whether you need a one hole rubber stopper, two hole stopper, or rubber bung with hole for tubing applications, we provide precise molded solutions based on your specifications.
