Most, however, only require the use of one hand. ![]() Quick disconnects are usually operated manually instead of automatically because many machines cannot not be programmed to respond to an unexpected change. Also, to make them more effective, manufacturers sometimes safe-tie quick connect disconnect couplings with wire. Typically, they offer couplings ranging in size from one eighth of an inch to ten inches in diameter. In addition to offering quick release couplings equipped with the ability to handle a wide range of high temperatures and high flow psi, manufacturers also offer couplings equipped to assist fluid transfer lines of a wide variety of sizes. When designing or assigning quick disconnect couplings, manufacturers think about a number of things, including application temperature range, application pressure (psi) range, application fluid flow type, flow line diameter, and frequency of use. Plastic couplings are becoming more popular because they cost less to make and exhibit excellent corrosion resistance. While manufacturers make the majority of couplings from metal, they are starting to make more and more from plastic. Manufacturers also offer quick disconnect couplers made from a variety of plastics. For higher flow applications, manufacturers often select stainless steel. Some of the materials available for coupling fabrication include metals like carbon steel, stainless steel, copper, brass, nickel-plated brass, bronze, and aluminum. Manufacturers select coupling fabrication materials based on the types of liquids they will be helping transport and the application details in general. Today, manufacturers use quick disconnect couplings for a diverse set of applications, from connecting garden hoses to connecting oxygen lines. Those pneumatic couplings that they used before not only had to be applied and removed with tools, but they were also stubborn and slowed down service people and their use of vehicles and equipment.Īfter the war, manufacturers realized the general usefulness of quick disconnect couplings and expanded their use. They wanted couplings that they could apply and remove more easily than pneumatic couplings. The first quick disconnect coupling products were commissioned by various governments for the military during World War II. Quick disconnect couplings are important to emergency service applications including emergency decontamination, emergency oxygen supply, and firefighting. For instance, because aircraft fuel is extremely combustible, aircraft fuel tank hoses are all equipped with dry disconnect couplings they reduce spillage that could lead to fires or fume inhalation. Safety applications in which quick disconnect couplings are key include those in the aerospace, fuel, and first response industries. Quick disconnects are simple products, but they are important to all applications that could potentially require an easy and fast solution to fluid spillage or mingling.Įfficient flow applications and products that quick disconnect couplings serve include agricultural sprayers, automotive systems, chemical and food processes, shut-off valves, ball valves, construction, firefighting hoses, and gas transfer. Quick Disconnect Manufacturers List Applicationsįluids with which quick disconnects commonly work include air, chemicals, fuel, gas, hydraulic fluids, oil, solid transfer, steam, and water. ![]()
