PVC bushing is a transition fitting used to connect pipes of different sizes in a pipeline system. Its core function is to achieve seamless connection between pipes of different specifications by reducing or expanding the size of the pipe interface, ensuring sealing effect and transmission efficiency. PVC bushing can efficiently connect large-diameter pipes and small-diameter pipes, so it is widely used in various scenarios that require pressure regulation, flow rate regulation, size conversion and medium diversion. 

PVC bushing is connected by threads or glue, which is tight and reliable, and the interface is not prone to leakage. At the same time, it also has a high cost performance, good physical properties, and wide applicability, can withstand corrosion from media such as acids, alkalis, and salts, and has good pressure bearing capacity. Due to these excellent qualities, PVC bushing is widely used in pipeline systems such as building pipelines, industrial pipelines, agricultural irrigation, and sewage treatment.
