High-pressure hose connector, the connecting thread is British pipe thread, external thread. The notable feature of this connector is that the threaded connection part can be rotated, which brings great convenience to the connection. It can be easily screwed with the fixed internal thread, and the high-pressure hose will not be twisted or deformed due to the connection of the connector, thereby causing damage to the reinforcement layer of the high-pressure hose, resulting in quality problems and affecting the service life of the hose; the connection part between the connector and the high-pressure hose adopts a barb shape, so that when the hose is tightened, the connector can firmly lock the hose without the glue falling off, and can ensure long-term use under high pressure. This barb-shaped form is widely used in the design of connectors and is the commonly used and strongest connection form between connectors and hoses; the connector is made of high-quality carbon steel, which ensures strength and has a certain toughness. The surface of the connector is galvanized, which can effectively prevent corrosion and can be used for a long time in ordinary media.
