Although the main function of air conditioning pipes in the entire air conditioning system is overflow, they also face high temperature, high pressure and vibration in the working environment. However, in the factory, each air conditioning pipe will undergo double air sealing after production is completed. After passing the test twice, the next step can be carried out.

The air tightness test is our last review of the product, but it is by no means our end. We will continue to listen to the voice of the market and constantly optimize our processes, because we believe that only by continuous progress can we win the continued trust of our customers.
