The nozzle brass is made of brass, which is not easy to rust, corrode, and has a longer service life. The joint is firm in connection, strong in crushing capacity, good in sealing and repeatability, convenient in installation and maintenance, and safe and reliable in operation. Its working principle is to insert the steel pipe into the ferrule, lock it with the ferrule nut, press against the ferrule, and cut it into a tubular seal. There is no need to connect and weld with steel pipes, which is conducive to fire prevention, explosion protection and high-altitude operations, and eliminates the disadvantages caused by inadvertent welding.
