Description
The heater flap vent seal for the 1968-1979 VW Bus, is a critical component for maintaining the integrity of the front fresh air flap system. This rubber seal ensures that the flap closes securely, preventing cold air, rainwater, or debris from entering the vehicle’s interior when the vent is shut. Over time, the original seals degrade—hardening, crumbling, or disappearing entirely due to age and exposure—making replacements essential for proper function. Below is additional information based on available data tied to this part number and related details.
This seal is designed specifically for the Bay Window Bus models produced between August 1967 and July 1979. It fits both the left and right sides of the front air flap assembly behind the grille, and two seals are required per vehicle. The part is typically glued onto the valve, ensuring a snug fit. Historically, this seal became obsolete from Volkswagen for many years, but we offer this aftermarket high quality replacement to meet the needs of classic VW restorers. The C&C seals are noted for their German-quality construction, aimed at replicating the original equipment manufacturer (OEM) standards.
Related part numbers sometimes appear in listings due to catalog variations or updates. For instance, 211259157A is occasionally referenced alongside 211259157, suggesting a possible revision or alternative SKU used by Volkswagen or suppliers. However, both numbers generally point to the same component: the rubber seal for the heater box intake flap.
The 211259157 seal is part of the broader heating and ventilation system in the Bay Window Bus. It works in tandem with other components like the heater boxes and control flaps (e.g., 021256205K for the left and 021256206K for the right, used in 1972-79 Bus models). Without a functional seal, the system fails to block unwanted airflow, leading to discomfort in colder weather—a common complaint among owners of un-restored buses. Replacement seals are sold individually.
Installation is straightforward: the old, degraded rubber is removed, and the new seal is glued into place on the flap valve. Owners are advised to inspect related components—like the accordion tubes and flapper boxes—for wear during replacement to ensure the entire heating system operates effectively.
This hard to find part’s re-availability has been a boon for enthusiasts, as it addresses a long-standing issue in maintaining these iconic vehicles. If you’re restoring a 68-79 VW Bus, this seal is a small but vital piece to keep the cabin comfortable and dry.
