Why Replace Your Side Cowl Vent Door Gasket?

The side cowl vent was designed to provide fresh outside air to the cab, but the vent door also needs to seal properly when closed.

After decades of exposure to weather, heat, and age, the original rubber gasket can become hard, brittle, cracked, compressed, or completely missing.

Replacing the gasket helps restore the seal around the side cowl vent door while also providing a cleaner, more finished appearance during a restoration.

It's an especially good item to replace while the vent assembly or surrounding cowl area is already apart for bodywork or restoration.
