Only the Sealtite PlastiplugTM combines advanced polymer technology with a unique, patented edge                   design to provide the perfect seal in concrete applications. The specially formulated readily conforms                      to irregular hole surfaces, but is hard enought to maintain the seal integrity. The "one-way" flanged edge           makes the Sealtite PlastiplugTM non-reversing and it won't back out under vapor pressure.
