An Oval Blind Rubber Grommet closes its center with a rubber membrane. The outer section retains the part in an oval panel opening, while the membrane covers the area that would be open in a conventional cable grommet. Understanding these separate features makes inspection more useful than checking the visible face alone.
A membrane may look intact even when a retaining lip has rolled beneath the panel. Conversely, a firmly seated perimeter does not make a punctured center suitable for an opening intended to remain covered. Examine the rounded ends and the center independently after fitting.
Match the groove depth and oval outline without stretching the body to make its face appear flush. Select the compound for the installation environment.
During nearby wiring work, keep cable ends and pointed tools away from the closed surface. If the covered opening needs a future cable passage, use an appropriate entry design. An unplanned hole through the membrane changes the part and should not be treated as an equivalent installation.
Photos illustrate structure or material only. The outer section retains the part in an oval panel opening, while the membrane covers the area that would be open in a conventional cable grommet. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.
FIND THE RIGHT FIT
Choose a through-hole or blind-hole profile, then compare the dimensions for your panel and cable arrangement.
