IAP 113611817A Brake Master Cylinder Reservoir Grommet

The IAP 113611817A is a brake master cylinder reservoir grommet designed for classic air-cooled Volkswagen vehicles. This rubber seal provides a critical connection between the brake fluid reservoir and the master cylinder, preventing leaks and maintaining proper hydraulic pressure in your braking system.

Key Features:

• Direct replacement for OEM part number 113611817A
• High-quality rubber material resistant to brake fluid degradation
• Approximately 18mm outer diameter x 12mm inner diameter
• Installs into the top of the master cylinder to secure the reservoir feed tube
• Prevents brake fluid leaks and air intrusion into the hydraulic system
• Also supersedes part number 357611817

Application:

Compatible with Volkswagen Beetle (1967-1979), Super Beetle (1971-1979), Karmann Ghia (1967-1974), Bus/Type 2 (1967-1979), Type 3 (1967-1974), Thing (1973-1974), and Vanagon (1980-1991). This is the larger diameter grommet used on many classic VW master cylinders. Note that some master cylinder configurations require two grommets depending on the reservoir style.

Why Replace:

Over time, rubber grommets can become porous, cracked, or degraded, leading to brake fluid leaks or allowing moisture and air into the brake system. A faulty seal can compromise braking performance and create dangerous driving conditions. Regular inspection and replacement of these seals is essential for maintaining safe, reliable braking in classic Volkswagen vehicles.
