High-pressure hose connector, the connecting thread is metric M22 internal thread, which can be rotated. The head of the connector is a Ø14 pin with an O-ring. This connector is a high-pressure hose connector commonly used in cleaning machinery. The matching thread is an M22 external thread, and the inner hole of the connector is Ø14. In this way, when the thread is screwed together, the pin is inserted into the hole, and the O-ring on the pin forms a seal, which is simple and convenient. The connection is firm and durable, can withstand high pressure, and is easy to disassemble. In addition, the nut shell is covered with plastic, and the plastic shape is like a gear, which is convenient for hand-holding and screwing. , the plastic has good anti-scalding performance, and the hot water medium will not be very hot to the hands; the connection part between the pipe joint and the high-pressure hose adopts a barb shape, so that when the hose is fastened, the pipe joint can firmly lock the hose without glue falling off, and can ensure long-term use under high pressure. This barb-shaped form is widely used in pipe joint design and is the commonly used and strongest connection form between pipe joints and hoses; the pipe joint is made of high-quality carbon steel, which ensures strength and has a certain toughness. The surface of the pipe joint is galvanized, which can effectively prevent corrosion and can be used for a long time in ordinary media.
