This rubber sealing ring fits the coupling (muff) of shower, sink or bathtub waste systems to prevent leaks at pipe joints.

## Long description

Gasket for waste coupling CERSANIT AQUA SYSTEM 40/50 is a rubber sealing ring designed to provide a watertight connection between the waste coupling (muff) and 40 mm or 50 mm drainage pipes. Intended for use with CERSANIT Aqua System fittings, the gasket fits into the coupling joint to prevent leaks where shower, sink or bathtub drain pipes connect. The part is suitable for replacement during repairs or new installations in both residential and commercial plumbing systems.
Advantages
The gasket is made of flexible rubber that ensures a reliable seal around pipe diameters of 40 mm and 50 mm. Its shape matches the coupling profile used in CERSANIT Aqua System waste fittings, which simplifies installation and reduces the risk of misalignment. Made for durability in wet environments, the material resists compression and maintains sealing performance when correctly fitted.
Suitable for
 Sealing waste coupling joints of showers with 40 mm or 50 mm drain pipes
 Sealing sink waste connections using compatible Aqua System couplings
 Replacing worn or damaged gaskets in bathtub drainage assemblies
 Maintenance and repair work in residential and commercial bathrooms
Key specifications
 Material: rubber sealing compound suitable for wet environments
 Compatible pipe diameters: 40 mm and 50 mm
 Application: waste coupling (muff) seal for shower, sink and bathtub drains
 Form: ring gasket shaped to fit Aqua System coupling profile
How to use
Ensure the coupling and pipe ends are clean and free of debris before installation. Insert the gasket into the coupling socket so that it seats evenly around the inner circumference. Push the pipe into the coupling until the gasket compresses and the joint is fully engaged. After assembly, check the connection for leaks by running water through the drain and re-tighten or re-seat the gasket if any seepage occurs.
Usage recommendations
For reliable long-term performance, avoid using petroleum-based lubricants on the rubber gasket. Replace the gasket if you observe cracks, hardening, or persistent leaks. When performing repairs, verify that pipe diameters and coupling type match the gasket specification to ensure a proper seal.
