The grooved reducer coupling is designed to connect grooved pipes with different nominal diameters, providing a smooth and reliable transition between pipeline sizes. Using a standard grooved connection method, it reduces installation complexity compared with traditional welded reducers while maintaining excellent sealing performance for both new installations and pipeline renovation projects.
Features
- Provides smooth transitions between different pipe diameters.
- Standardized design enables quick and easy installation.
- Ductile iron body offers excellent mechanical strength and durability.
- Reliable sealing suitable for various conveying media.
- Available in multiple sizes for compatibility with other grooved fittings.

Applications
The grooved reducer coupling is commonly used in fire protection piping, hot and cold water systems, HVAC installations, municipal water supply, industrial production lines, wastewater treatment plants, and underground utility tunnels where pipe size transitions are required.
