Material: UPVC (Unplasticized Polyvinyl Chloride). High-quality raw materials are injection-moulded from UPVC, with surfaces polished for an aesthetically pleasing finish. Use: Punch holes on the pipe wall, cover the outer wall of the pipe with the arc surface of the joint, and use it instead of the tee in the pipeline where it is inconvenient to use, or as a repair joint for the rupture of the pipeline.
