Rubber gaskets are critical components in ensuring airtight sealing in industrial HVAC systems. Over time, they can degrade due to heat, chemicals or pressure. A single worn gasket can lead to system failure or downtime, so regular maintenance is essential.

Here’s a practical 10-point checklist to help you inspect and maintain rubber gaskets effectively.
