Most of the hose clamp used in the market are metal hoses, and the specifications of metal joints need to match the specifications of metal hoses.
 The types of metal joints are mainly divided into three categories: threaded connections, flange connections and quick connection joints. Metal joints are recommended to use stainless steel materials to prevent rust and also have the characteristics of high temperature resistance and corrosion resistance. Such characteristics make their application fields change. To be broader.
 The specific models of metal joints are as follows: (DPJ joint, DKJ joint, DGJ joint, 90 degree joint, 45 degree joint, Y joint, T joint)

1. DPJ connector
DPJ external thread end-type metal joints are made of zinc alloy die-casting, the surface is galvanized, frosted, or chrome-plated; the advantages are: compact structure, no pores, high strength, beautiful appearance;
DPJ metal connector
2. DKJ connector
DKJ card sleeve type connector can connect non-threaded steel pipe and hose, without threading process, just screw in the screw;
DKJ connector
3. DGJ connector
DGJ self-fixing metal joints can connect unthreaded steel pipes or unthreaded equipment outlets to hoses, eliminating the need for threading processes; metal joints are made of zinc alloy die-casting, and the surface is galvanized, sanded, or chrome-plated; The appearance is beautiful and shiny; self-fixing joints are used to connect metal hoses to unthreaded steel pipes or unthreaded equipment outlets.
DGJ connector
Four, 90 degree joint
90-degree elbow joint thread specifications: inch thread (G), product material: A, C, F parts are made of steel. D is made of die-cast iron. Color type: metallic color (silver white), working temperature: -40 ℃ to 100 ℃, instant heat resistance over 120 ℃.
90 degree joint
Five, 45 degree connector
45-degree elbow joint thread specification: inch thread (G), A, C, F parts are made of steel, D is die-cast iron, adjustable angle range is 45 °, can be fixed at any position, metallic color (silver White) 40 ℃ to 100 ℃, instant heat resistance up to 120 ℃. After joining, it is 45 degrees to the box body, thickened zinc alloy, beautiful appearance, compact structure.
45 degree joint
Six, Y-shaped T-shaped three-way joint
 One end of the connector is connected to the thin steel wire tube, and the other end of the metal connector is connected to the metal hose: the metal connector is made of zinc alloy die-casting, the surface is galvanized, frosted, or chrome-plated; the structure is compact, no pores, and high strength. Reliable connection with metal hose, beautiful appearance;
Y-shaped three-way joint
 In addition to the selection of the metal joint, it needs to be determined according to the metal hose, but also according to the actual use. Different liquid gas temperature and pressure are different. The types and specifications of the joints used are different. The use of the environment can make the selected cost-effective
