Fel-Pro 416 Engine Coolant Pipe O-Ring

Fel-Pro 416 Engine Coolant Pipe O-Ring

Fel-Pro 416 is an engine coolant pipe O-ring made from nitrile for sealing coolant passages in select Volkswagen applications. It is sized for a 13/16 in. inside diameter, 1 1/16 in. outside diameter, and 1/4 in. width to support a precise seal where the coolant pipe meets the engine or related cooling components.

Key Features

• Nitrile material for coolant sealing applications
• Inside diameter: 0.812 in. (13/16 in.)
• Outside diameter: 1.062 in. (1 1/16 in.)
• Width: 0.250 in. (1/4 in.)
• Engine coolant pipe O-ring for sealing system service
• Fel-Pro 416 part number for direct identification

Application Details

Compatible with Volkswagen Jetta, Volkswagen Golf City, Volkswagen Jetta City, Volkswagen Golf, and Volkswagen Beetle applications listed in the fitment data. This Fel-Pro 416 coolant pipe O-ring is used in sealing-system service where a correctly sized elastomer seal is needed to maintain coolant containment and connection integrity. This part cross-references Dayco 72211 for the same application.

Common Issues This Part Can Address

• Coolant seepage at the pipe-to-housing sealing point
• Visible wetness around the coolant pipe connection
• Loss of seal integrity from a worn or flattened O-ring
• Service replacement during cooling system repair
• Fitment-specific sealing needs on Volkswagen Jetta and Volkswagen Golf platforms

Installation Notes and Tips

Inspect the sealing groove and mating surfaces before installation. Clean away old coolant residue, debris, and any damaged elastomer material so the new O-ring seats evenly. Apply clean coolant or the lubricant specified by the service procedure to help prevent twisting or pinching during assembly. Verify the part dimensions and vehicle application before reassembly, especially on Volkswagen Beetle, Volkswagen Golf, and Volkswagen Jetta cooling system repairs.

Quality Assurance

Fel-Pro gaskets and sealing components are built around application-specific materials and sealing requirements for professional repair use. Fel-Pro 416 follows that approach with a nitrile construction selected for coolant sealing service.
