Direct answer
Install an adhesive vent on a clean, dry and compatible flat surface; align the active area with the opening, avoid touching or damaging the membrane, apply controlled pressure to the adhesive ring and allow the specified dwell time before validation.
Prepare and place the part
Remove oil, dust, release agents and moisture using a cleaning method compatible with the housing. Let the surface dry, handle the part by its liner or adhesive edge, and use a fixture when alignment or repeatability is critical.
Bond and verify
Apply uniform pressure to the adhesive area without pressing the exposed membrane. Respect the adhesive supplier's temperature and dwell-time guidance. Verify appearance, position and bond continuity, then test representative assemblies for airflow or acoustic performance and ingress protection.
