The compression pipe fitting consists of three parts: joint body, ferrule, and nut. When the ferrule and the nut sleeve are inserted into the joint body on the steel pipe, and the nut is tightened, the outer side of the front end of the ferrule fits the conical surface of the joint body, and the inner edge evenly bites into the seamless steel pipe to form an effective seal. The ferrule type straight-through terminal joint is easy to install and has high pressure resistance, so it is widely used.
