When specifying a solid rubber grommet, confirm whether the required part is a closed plug or an open component made from solid rubber. The drawing must define the intended interface.
For a closure, check the opening, panel thickness and retaining features. If gas or liquid sealing is required, specify the substance, pressure, temperature and acceptance criteria. A general plug does not establish a containment rating.
Select the compound for the actual exposure and verify the fitted assembly. Chemical resistance, vibration performance and long-term retention cannot be guaranteed from the word solid or from rubber alone.
