Description
This polypropylene threaded reducing bush provides a practical solution for connecting two different sizes of threaded fittings within a PP pipework system. It allows a larger female threaded outlet to be reduced down to accept a smaller male threaded connection, without the need for additional adaptors or complex pipework changes.
Manufactured from high-quality polypropylene, the reducing bush offers strong chemical resistance and reliable performance in low-pressure applications. Its compact, all-threaded design makes it ideal for space-restricted installations where maintaining system flexibility is important.
As part of the threaded polypropylene range, this fitting is pressure rated to 6 bar and is commonly used in systems where corrosion resistance and ease of modification are essential.
Key Features & Benefits
