Overview
The Threaded Grooved Reducing Tee is designed to create a reduced threaded branch outlet from a grooved main pipeline. It enables efficient branching where the outlet size is smaller than the main pipe, making it especially suitable for systems that commonly use threaded connections on small-diameter branch lines. This fitting combines the advantages of grooved installation speed and threaded connection compatibility, offering a practical and reliable solution for complex piping networks.
Product Description
This fitting features a grooved inlet and outlet for the main pipeline, along with a threaded branch connection for reduced-size piping. It allows branch lines to be installed directly without welding or cutting, significantly reducing installation time and labor requirements. The compact structure supports precise flow diversion while maintaining system pressure and sealing performance. Clearly cast markings provide essential technical information such as certification status, pressure rating, and branch size for easy identification during installation and inspection.
