[0002] Pipeline connectors are a general term for various parts used to connect pipelines. They mainly include elbows, tees, crosses, reducers, pipe clamps, unions, flanges, bolts, nuts and other components. The function of these connectors is to connect individual pipes to form a complete pipeline system, realize the functions of fluid (such as liquid, gas, etc.) transportation, distribution, diversion, etc., and ensure the sealing, stability and reliability of the connection parts to prevent leakage and other problems. They play a vital role in pipeline engineering in various industrial, civil and other fields.

[0003] In the connection of bifurcated pipelines, pipe connectors such as hard rubber tees are often used to connect hoses in order to prevent the hoses from loosening during assembly production, especially during transportation and user use.
