VIEGA Viega 3811 pipe fitting / component, inner diameter 100 mm

VIEGA Viega 3811 pipe fitting / component, inner diameter 100 mm is a plumbing connector designed for use within compatible Viega piping systems. Manufactured from plastic and featuring a lip seal, this inline component provides a 100 mm internal passage for fluid transport and is intended for installations where that diameter and a sealed joint are required. The part is suitable for sanitary applications including WC connections and other drainage or waste systems that match Viega system geometry.

Advantages

The component combines a 100 mm internal diameter with a molded lip seal to ensure a secure, watertight joint without additional sealing materials. Being made of durable plastic, it resists corrosion and is lightweight for easier handling during installation. Its design follows Viega system standards, which supports compatibility and predictable fit within matching Viega connectors and pipes.

Suitable for

• WC and sanitary waste connections requiring 100 mm internal diameter
• Residential drainage systems integrating Viega components
• Commercial sanitary installations with matching system interfaces

Key specifications

• Inner diameter: 100 mm
• Material: plastic
• Seal type: integrated lip seal

How to use

Prepare mating pipes or fittings by ensuring end faces are clean and free of debris. Align the Viega 3811 component with the corresponding pipe or connector and insert until the lip seal seats evenly. Check that the component is fully engaged and that the seal is not twisted or damaged. After assembly, verify the connection for alignment and perform a water test according to local plumbing codes to confirm a leak-free joint.

Usage recommendations

Use this plastic fitting only with compatible Viega system parts and matching 100 mm pipe elements. Avoid exposure to open flames or solvents that could degrade plastic. Follow local installation standards and pressure/temperature limits specified by the overall piping system; inspect the lip seal before installation and replace the component if any damage is found.
