[0026] Specifically, the plastic rod tee body 1 has only one metal connecting cap 2 at its port for connecting to other pipe fittings, while the other two plastic rod ports are connected to plastic pipes to branch the pipeline. The inner wall of the metal connecting cap 2 has an internal thread 3, which can be screwed into the corresponding external thread 4 of the plastic rod tee body 1 to ensure a stable connection. Next, the sealing rubber ring 5 in the annular groove 6 of the corresponding port of the plastic rod tee body 1 is squeezed when the metal connecting cap 2 is tightened, thereby filling the connection gap and achieving a sealing and leak-proof effect. When a port is not needed, the sealing cap 7 can be connected to the metal connecting cap 2 through the thread to close the port and prevent impurities or dirt from entering the pipeline. When in use, simply unscrew the sealing cap 7. For ease of operation, the surface of the plastic rod tee body 1 is provided with anti-slip texture 8, while the outer side of the metal connecting cap 2 is designed with raised ribs 9 to increase friction, making it easier to grip and screw during operation, thus smoothly completing the installation or disassembly work.

[0027] Working principle: The plastic rod tee body 1 connects to other pipe fittings only at one port with a metal connecting cap 2, while the other two plastic rod ports connect to plastic pipes to branch the pipeline. Then, the inner thread 3 of the metal connecting cap 2 engages with the corresponding external thread 4 of the plastic rod tee body 1 for fixation. The sealing rubber ring 5 in the annular groove 6 of the corresponding port of the plastic rod tee body 1 is squeezed when the metal connecting cap 2 is tightened, filling the gap and achieving a seal to prevent leakage. When the port is not in use, the sealing cap 7 is connected to the metal connecting cap 2 through the thread to close the port and prevent impurities from entering. It can be unscrewed when needed. During operation, the anti-slip texture 8 on the surface of the plastic rod tee body 1 and the raised ridges 9 on the outer side of the metal connecting cap 2 increase the friction, making it easy to grip and twist, and completing the installation and disassembly.
