In industrial production, equipment maintenance and daily life, the transmission of heat media such as hot water and steam is ubiquitous. However, when traditional metal quick connectors are transmitting heat media, the surface temperature is often too high, which poses a risk of scalding and affects operational safety and efficiency. In order to solve this problem, we have launched this quick coupling with plastic housing to provide you with a safe, efficient and reliable heat medium transmission solution. The biggest highlight of this quick connector is its unique plastic shell design. Compared with ordinary metal connectors, the plastic shell has an extremely low thermal conductivity, which can effectively block the heat of the heat medium from being transferred to the surface of the connector. Even if it is used for a long time in a high-temperature hot water or steam environment, the connector shell can maintain a suitable temperature. Operators can touch it directly without worrying about the risk of scalding, which greatly improves operational safety.
