A Quick Connect Hydraulic Coupling, also called a quick disconnect or quick release coupling, is a coupling used to provide a fast, make-or-break connection of fluid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections, which require wrenches. When equipped with self-sealing valves, quick connect fittings will, upon disconnection, automatically contain any fluid in the line.
YH Hydraulic quick disconnect couplings maximize ease of use and system uptime in key hydraulic and pneumatic applications and markets such as life sciences, industrial and mobile equipment, nuclear power, oil and gas exploration, agriculture, construction, mining, food and beverage, mobile HVAC, process cooling water supply and more.
Stainless Steel Quick Coupling
7241ASS quick couplings are made from stainless steels. These quick couplings are widely used in connections of various machines such as loaders, excavators, elevators, other hydraulic systems, etc.. YH quick coupling are ensured to be with good sealing, high pressure tolerance, and good looking.
