Pipe Plugs Rubber
When you talk about pipe plugs, more often than not, you talk about those large pneumatic tools that are used to seal pipes in sewers or water line systems. Whether it is maintenance that needs to be done, some testing or even some kind of a repair, it doesn’t matter, a pipe plug really comes in handy. They are inserted into a pipe to seal off one end of the pipe, so the liquid from inside can’t come out and you can do what you have to do.
However, aside from those large form factor pipe plugs, there are also pipe plugs rubber, that are used for small scale projects and handy work. Most commonly, pipe plugs rubber are used in plumbing. They act as a seal, to stop the flow of liquids, so that whatever work that needs to be done, can be done. Pipe plugs rubber aren’t usually made for single use. More often than not, they are a tool or piece of equipment that is being reused time after time again.
This is possible because rubber is an excellent material that doesn’t decay fast and can be used in various harsh settings. A pipe plug rubber that is used for plumbing is not your everyday plug. Since these plugs are meant to be removed and reused, they often come with wing screws for easier insertion and removal. Naturally, since these are reusable products, you need to take proper care of them. You should wash your pipe plugs rubber after every use, either with water and detergent or with high-pressure devices.
Pipe plugs rubber can be made from various rubber materials such as natural rubber, neoprene, EPMD etc. Additionally, they come in various sizes, as well, but if need be, we could provide you with a custom shaped and sized pipe plug to match your needs.
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.
