## Summary description

Reducing sleeve coupling VIEGA 100/90 designed for transitioning between pipes with 100 mm and 90 mm diameters. Suitable for plumbing and drainage systems where size adaptation is required. Provides a compact mechanical connection for compatible pipe materials; used in renovation, sewer, and stormwater installations to connect different diameter pipes reliably.

## Long description

The VIEGA Reducing Sleeve Coupling 100/90 is a mechanical pipe transition designed to connect pipes with outer diameters of 100 mm and 90 mm. Intended for plumbing, drainage and sewer applications, the coupling provides a compact connection that accommodates a change in pipe size while maintaining flow alignment. The product is suitable for repair, renovation and new installations where a reliable adaptation between these two diameters is required.
Advantages
The coupling offers a simple, space-saving solution for adapting between 100 mm and 90 mm pipes without the need for complex fittings or extensive pipework modification. Constructed to provide a secure mechanical joint, it ensures a stable alignment of connected pipes and reduces installation time compared with custom-cut transitions. Its straightforward design makes it compatible with common installation conditions in residential and commercial drainage systems.
Suitable for
Transitioning between sewer or stormwater pipes with 100 mm and 90 mm diameters
Renovation and repair of existing drainage runs where diameter reduction is required
Compact installations where space is limited and a direct sleeve coupling is preferred
Key specifications
Type: reducing sleeve coupling for pipe diameter transition
Connection sizes: 100 mm to 90 mm outer diameter
Application area: plumbing, drainage, sewer and stormwater systems
Design: compact mechanical sleeve for direct pipe adaptation
How to use
Select the correct coupling for the pipe materials and outer diameters being joined. Ensure pipe ends are clean, free of damage and cut square. Slide the coupling onto the larger or smaller pipe end as appropriate, align the pipes to maintain flow direction, and complete the mechanical clamping or sealing method recommended for the coupling type and pipe material. Verify the connection for proper alignment and any specified sealing before returning the system to operation.
Usage recommendations
Use the reducing sleeve in installations where the pipe materials and wall thicknesses are compatible with a mechanical sleeve connection. Confirm compatibility with local codes and system requirements, and follow VIEGA installation guidelines when available. For buried or pressurized applications, ensure appropriate bedding, support and inspection to maintain long-term performance.
