	I. Product Definition and Core Advantages

	A quick coupling is an industrial component that enables rapid connection and disconnection of pipelines without tools, widely used in fluid transmission scenarios such as hydraulics, pneumatics, cooling, and lubrication. Its core advantages focus on three dimensions:

	
			Efficiency Improvement: Traditional threaded connections take 5-10 minutes to assemble and disassemble, while high-quality quick couplings can achieve rapid docking within 10 seconds. In scenarios such as equipment maintenance and production line switching, it can reduce downtime by more than 80%;
		

	
			Safety Assurance: Adopting a double-seal structure design, it can achieve "zero leakage" when disconnected, avoiding waste of media such as hydraulic oil and coolant and environmental pollution, while reducing the risk of operators coming into contact with hazardous media;
		

	
			Strong Adaptability: It can withstand extreme temperatures from -40℃ to 150℃, with pressure resistance ranging from 0.1MPa to 100MPa, suitable for various transmission media such as water, oil, and gas, meeting the working conditions of different industries such as mining, automotive, and new energy.
		

	II. Main Types and Industrial Applications

	According to structural and functional differences, quick couplings are mainly divided into the following three categories, corresponding to different application scenarios:

	
			Hydraulic Quick Couplings: Adopting high-pressure sealing technology, they are suitable for hydraulic systems of construction machinery and mining equipment, such as the connection of excavator hydraulic pipelines. They can withstand high pressure of 30-60MPa to ensure continuous operation of heavy equipment;
		

	
			Cooling Quick Couplings: Focusing on low resistance and high flow, they are used for new energy vehicle battery cooling and industrial machine tool coolant circulation. For example, in the cooling circuit of new energy vehicle battery packs, they can achieve a flow transmission of more than 1.5L per second to ensure constant temperature operation of the battery;
		

	
			Pneumatic Quick Couplings: Emphasizing lightweight and high-frequency insertion/extraction, they are suitable for pneumatic tools and automated production lines, such as the connection of AGV robot pneumatic grippers. The service life of a single insertion/extraction can reach more than 500,000 times, meeting the high-frequency operation needs of automated equipment.
		

	III. Market Trends and Development Directions

	With the rapid development of industrial automation and the new energy industry, the quick coupling industry presents three major trends:

	
			Intelligent Upgrade: Intelligent quick couplings integrated with pressure sensors and temperature sensors are gradually becoming popular. They can real-time monitor pipeline pressure and flow data, and upload them to the control system through the Internet of Things to realize leakage early warning and remote diagnosis, conforming to the development needs of Industry 4.0;
		

	
			Material Innovation: The application of new materials such as 316L stainless steel and PEEK polymer materials has improved the corrosion resistance of quick couplings by 3 times, and the salt spray test life has been extended from 500 hours to 1500 hours, suitable for highly corrosive scenarios such as chemical industry and marine engineering;
		

	
			Customized Services: In response to the special needs of emerging industries such as new energy and semiconductors, enterprises have launched "customized solutions". For example, the special quick couplings for hydrogen supply circuits of hydrogen fuel cells can achieve -40℃ ultra-low temperature sealing and 100MPa high-pressure resistance, filling the industry gap.
