VIEGA replacement gasket for Geberit sink siphon (model 1473867) – sealing ring for washbasin trap

Replacement sealing gasket from VIEGA designed for use with Geberit-style washbasin siphons. This sealing ring serves as a wear part for washbasin traps, providing a watertight connection between siphon components to prevent leaks and ensure correct drainage flow. The gasket is intended for repair and routine maintenance of bathroom sinks where a compatible ring has deteriorated or been lost.

Advantages

The gasket is manufactured to match the dimensions and sealing requirements of common washbasin siphons used in residential and commercial bathrooms. It restores the original sealing function of the trap, reduces the need to replace larger siphon assemblies, and provides a simple, low-cost service solution. The part is resistant to normal bathroom conditions and helps maintain reliable drainage performance when properly installed.

Suitable for

• Repairing leaks in washbasin siphons and traps
• Routine maintenance of bathroom sink drainage
• Replacing worn or damaged sealing rings in residential and commercial sinks

When it may not be suitable

This sealing gasket is intended for specific Geberit-style washbasin siphon geometries; it may not fit siphons with non-standard dimensions or proprietary designs. If the siphon body is cracked, severely corroded, or otherwise damaged, replacing the entire siphon assembly rather than only the gasket is recommended.

Key specifications

• Function: sealing ring for washbasin trap
• Material: elastomeric sealing material suitable for sanitary use
• Application: indoor bathroom sink siphons and traps
• Primary purpose: prevent leaks and ensure proper drainage connection

How to use

Shut off water supply to the washbasin and remove the siphon or trap components according to the siphon manufacturer’s instructions. Inspect mating surfaces and clean away debris or old sealant. Fit the replacement gasket into the designated groove or contact area, then reassemble the siphon parts, ensuring correct alignment and compression of the sealing ring. After reassembly, check for leaks by running water and visually inspecting joints; retighten connections if necessary.

What to consider before purchase

• Confirm compatibility with your washbasin siphon geometry and dimensions
• Inspect the siphon for structural damage that would warrant full replacement
• Verify that the gasket material is suitable for your local water conditions and usage

Usage recommendations

For reliable sealing, replace any gasket that shows visible deformation, hardening, or cracking. Use correct torque and hand-tighten fittings as specified by the siphon manufacturer; avoid over-tightening plastic components. Periodic inspection during routine maintenance helps prevent leaks and extends the service life of the siphon assembly.
