Because over decades the original sealing rings often become brittle, hard, compressed or cracked (due to heat cycles, age, vibration, exposure to cabin air, moisture and dust), they lose their ability to seal properly.
This can lead to:
• Unwanted air leaks or drafts into cabin
• Water or dust ingress into the interior or into heater ducts
• Poor heating or ventilation performance
• Increased cabin noise, wind-noise or fumes entering cabin (especially on vehicles with engine-bay to cabin vents).
Replacing with a correct-spec sealing ring ensures a tight, flexible seal that restores proper HVAC function, occupant comfort, and helps preserve the integrity of the car’s interior and ventilation system.
