1、Relatively common national standard connector double ferrule straight‑through connector, acts as a connection between steel pipes. Has simple and firm connection with good sealing, no welding, high pressure resistance and vibration resistance. 2、Suitable for complicated pipeline connections that cannot be welded, and pipeline systems that can pass gas, liquid, oil and general corrosion. 3、Compression ferrule connector is composed of three parts: the connector body, the ferrule and the nut. 4、When the ferrule and the nut are inserted into the pipe body, when the nut is tightened, the outer side of the front end of the ferrule is attached to the taper surface of the connector body, and the inner blade is evenly glued to the seamless steel pipe to form an effective sealing. 5、Ferrule type installation is environmental protection and reusable, easy to operate, convenient and free to disassemble.
