111-819-945 VW Beetle & Bus Heater Hose to Body Seal (1963-1979)

VW Heater Hose to Body Seal – 111-819-945

The 111-819-945 is a specialized rubber grommet designed to seal the entry point where the main heater hose passes through the vehicle’s body or tin-ware. This seal is crucial for maintaining the environmental integrity of your Volkswagen's cabin. It serves two primary purposes: it prevents engine heat and exhaust fumes from entering the passenger compartment, and it protects the heater hose from being chafed or cut by the sharp edges of the sheet metal.

Designed for a 50mm diameter hose, this seal is made from a durable, high-temp rubber compound that withstands the constant vibration and heat cycling common in air-cooled engines. Over time, original seals become brittle and crack, allowing road noise, moisture, and dangerous carbon monoxide to seep into the car. Replacing a worn seal is a simple but vital safety step in any restoration or heater system overhaul.

Installation & Maintenance Tips

• Check Your Hose Diameter: While 50mm is the standard, some aftermarket "Big Bore" heater systems use 60mm hoses. Verify your hose size before ordering to ensure a tight fit.

• Ease of Install: To make installation easier, apply a small amount of silicone spray or dish soap to the outer groove of the seal before pressing it into the sheet metal.

• Inspect the Hose: If your old seal was missing, inspect the heater hose for wear. If the metal has started to cut into the hose, it should be replaced to prevent heat loss.

• Tight Seal: Once the hose is pushed through, ensure the lip of the grommet is fully seated on both sides of the metal for maximum noise reduction.
