solid rubber stoppers
We manufacture our products according to the highest standards and tend to use solely premium raw materials during the production process. Thus the fact that solid rubber stoppers we produce rank high among top-quality solutions on the market. In a nutshell, the solid rubber stoppers we craft should deliver the standard features our customers would expect from a typical model. What makes them different from the alternatives are both the durability and uncompromised performance regardless of which external conditions you expose them to. Surely, when we say that our product delivers as expected, what we mean is that they will only leave the track when our craftsmen test their performance.
Therefore, expect our solid rubber stoppers to deliver enhanced protection from various environmental influences such as rain, hail, snow, and to perform as expected both in humid and dry environments. What is characteristic of the products we offer is that they work equally well in hot and cold surroundings. Namely, if the temperatures you expose solid rubber stoppers to do not exceed extreme values, our standard gear should insulate the enhanced item flawlessly, while it provides an air-tight environment at the same time. On the other hand, if you intend on exposing solid rubber stoppers we produce to extreme temperature conditions, we advise you to speak to our support team and introduce them to your situation.
Namely, we will gladly offer our expertise and make specific adjustments during the making process in order to meet your wants and needs. The point is that we have mastered the means of either potentiating or reducing specific features by carefully selecting the materials we use. Even though this endeavor could cost you a bit more than the basic solid rubber stoppers package, the benefits you would enjoy are too good not to be taken into consideration. Thus, inform us about what you need so we can customize it for you.
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.
