Rubber pipe plug
Rubber pipe plug and rubber pipe stoppers are something that is necessary for plumbers, but also for every person in the household. The rubber pipe plug is also finding its role in many industries. These are heavy-duty plugs that are made from the most durable types of rubber to be functional for many years. In addition to being used for sealing and finishing, they can also be used for aesthetic purposes. We offer a rubber pipe plug in any color you want, so you can close the gaping pipe hole and make it look better. Also, different colors can be important to be able to distinguish pipes.
Whether you choose one of the sizes that is already in our offer or you want to order custom plugs, it is very important that you know the exact size. When we say true, we mean completely true, where everything is precise to the millimeter. Only in this way can we make plugs and stoppers that will fully satisfy your needs, ie the purpose for which you need them. You need to know the length, diameter and thickness. Also, pay attention to whether there are any deviations that may affect the shape.
Once you’re sure of the size, the job isn’t over yet. With our help, you should decide on the material from which the rubber pipe plug will be made. Many different variations of rubber exist, and some of them have high temperature resistance, acid resistance, weather resistance, rebound resilience, abrasion resistance and many other characteristics. For example, silicone can be exposed to temperatures up to 300 degrees Celsius, while natural rubber is the most durable. This does not mean that other types of rubber are not durable, on the contrary, but natural rubber is particularly durable. FCM choose if you need high chemical stability and so on.
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
- Internal pipe-end closure
- Material options discussed
- Silicone and natural rubber / latex. Choose one formulation for the actual contact and loading conditions.
- Application focus
- Pipe or conduit ends. Size the part against the selected assembly.
- Dimensions to confirm
- Pipe bore, insertion length, plug body and retention hardware. Match these to pipe or conduit ends.
- Contact conditions
- Acids: define concentration, temperature and contact time, then check compatibility with the chosen compound.
- Exposure to evaluate
- Outdoor weather and rubbing or abrasion. Validate the selected material under the combined conditions.
- Closure retention
- Define the means of retention and any pressure differential before fitting the closure.
