Hose connector with nut

Material and Type: Common materials include stainless steel (such as 304 and 316, which are corrosion-resistant and suitable for sanitary or chemical environments) and carbon steel (high strength, low cost, commonly used in industrial hydraulic systems). The main body of the hose may be a metal bellows or a rubber composite tube. Types can be divided into crimped hose connectors (which are integrally formed with the hose through hydraulic crimping, suitable for high-pressure hoses) and ferrule-type connectors (which use ferrules to cut into the hose for sealing, facilitating easy disassembly and assembly). In addition, there are variants such as internal and external thread nut sets, which adapt to different interface specifications through the combination of internal and external threads.

Structure and working principle: The hose connector with nut is usually composed of a connector body, a nut, and a hose assembly (such as a corrugated hose or rubber hose). The connector body and the hose are connected by crimping, welding, or ferruling, while the nut is screwed onto the connector body through threads. During operation, the tightening force of the nut drives the sealing structure (such as conical surface fit, composite gasket, or O-ring) to deform, forming an end face seal or metal hard seal, thereby preventing fluid or gas leakage. Some designs adopt a double ferrule structure, which enhances vibration resistance and sealing reliability through the engagement of front and rear ferrules.
