A must have item on any work site is usually an air compressor to operate air powered tools. Since they are constantly being moved throughout the day and being used for various purposes, these machines require quick release couplings- also called quick disconnect or QR couplings. These couplings make it quick and easy to swap out tools as needed providing greater usability of the transfer line.
What are QR couplings?
A connector is a part that makes a leak-proof bond between a hose and machine or between two hoses. They are very uncomplicated to operate using a push/pull action. They have been labelled as safe and easy to use as plugging a lamp into the electrical outlet of your home. Their true efficacy is that they all decrease the amount of fluid lost upon disconnect.
Simply slide the sleeve of the coupling back and slip the adapter into the coupler. Push the sleeve forward to snap it into place. This opens the line's connection. To disconnect, turn off all fluids as an additional safety precaution. Pull back on the sleeve of the coupler, and the adapter should quickly release from it. No training is required because this push and pull motion is all the know-how you ever need to operate them properly.
What are QR couplings made of?
Most quick disconnects consist of brass bodies, but others are steel or lightweight plastic. However, this latter material does not hold up very well for long term use. Brass is the most common because it is durable and resists corrosion very well. In extremely demanding industrial applications, the couplings can be carbonized steel and may contain Teflon, neoprene, and nitrile. Where they are being installed matters greatly in the materials that should be utilized.
How are QR couplings installed?
Equipped with threaded ends that are similar to any screw, they can be effortlessly twisted into place. It is important to know that there are both male and female couplings, as well as weld ends, flanges, and hose shanks which are more applicable to commercial uses. All couplings have reinforced nut-like sections that allow them to be tightened into place with a wrench.
What are QR couplings used for?
These devices are commonly found anywhere air, gases, and liquids under pressure are being transferred. On construction sites where pneumatic hoses are utilized, they are the best option because they can rotate completely and make multi-directional work smooth and fast. They are also found on pneumatic conveyors in warehouses, in chemical and steel manufacturing plants, on furnaces, in trucking facilities, on railroads, and on deep sea drilling and offshore rigs for the transfer of petroleum and natural gas. Large bore couplings are even used in space when docking shuttles and supply craft.
QR couplings are also useful for home application. Many do-it-yourself pressure washing units have quick release couplings for the hoses and spray gun. Perhaps the most ingenious use was on the end of a standard garden hose. The coupling allowed the ease of adding and removing a very expensive Japanese watering wand for an artist's bonsai collection. The wand was too expensive to leave exposed to the elements, but the quick release coupling let him snap it on and off as needed.
Once the ease with which they are installed and operated is known, as well as how effectively they function, there will certainly be many more uses for quick release couplings on the job and in the home.
