The quick twist lock brass connector is a new type of pipe connection method in the field of cleaning machinery. It uses threads to screw together, internal and external threads to connect, and at the same time, the pin in the internal thread connector is inserted into the hole in the external thread connector, and it is sealed with an O-ring. It is convenient and practical, the connection is stable and firm, and can withstand high pressure; it is fast to connect and easy to disconnect, just unscrew the thread; its characteristics are that the thread is 4-start thread and the pitch is 6mm, so the ordinary thread is screwed 4 turns, and it only needs to be screwed once to achieve the screwing length of 4 turns of ordinary thread, so it is called a quick-twist lock connector; the connector body is made of brass, which has strong corrosion resistance and can be used for a long time in acid and salty media; there is a plastic sleeve outside the nut, which feels good and smooth to screw the nut, and can also play a scalding effect, making it suitable for use in hot water media; in addition, the surface of the connector is nickel-plated, which can better play an anti-corrosion role and will not turn copper green after long-term use
