What is the difference between tee and cross?
The core difference between tee and cross is the number of branch ports, which directly determines their shape, function, and applicable scenarios.
| tee | generate one branch. |
| cross | generate two branches. |

Diverting or merging |
Simultaneously diverting or converging in two directions |

Fluid path |
Supervisor → 1 branch pipe, or vice versa |
Supervisor → 2 opposing branches, or vice versa |

Application frequency |
Extremely high, it is one of the most common fittings in pipeline systems |
Lower, only used for specific layouts |
|
pressure distribution |
relatively simple |
More complex, may generate greater stress at the intersection |
TeE
It is a ubiquitous pipe fitting in pipeline systems.
It can also be divided into:
| Equal diameter tee | The three interfaces have the same diameter. |
| Reducing tee | The diameter of the branch pipe interface is smaller than that of the main pipe. |
Cross
It usually occurs in complex pipe networks that require symmetrical distribution or cross flow.
Summary
| Choose tee | When you only need to lead out one branch (or merge one branch) from the pipeline. |
| Choose cross | Only when your design requires simultaneous branching or merging in two vertical directions, and space is limited or the design is special. |

We are able to provide high quality tee according to customers' needs and look forward to your purchase.
