The Brass screw quick connector is a quick-connect fitting designed for liquid and gas transmission systems. The fitting achieves quick connection by spiral insertion and has strong pressure resistance, corrosion resistance, high temperature resistance and other characteristics. The plug part of the connector adopts a spiral design. The user connects the connector to the pipe or equipment at the other end by rotating the plug. This design not only achieves quick plugging and unplugging, but also can be installed and disassembled without additional tools. This quick-connect fitting is made through advanced precision machining technology. The thread and the sealing ring are extremely precise, ensuring the sealing and reliability of the connection. The inside of the connector is usually equipped with a highly elastic sealing ring, which can automatically tighten when spirally inserted to form an effective seal.
