So where can these fittings be found and how much do they cost? The answer for both of these questions varies vastly. To find one of these products you can look near or far, as far as kilometers underwater used in drilling operations or high in orbit around earth, for docking spacecraft. Also, you are able to find them as close as walking into a garage and finding a quick fittings on the air hose attached to the air compressor. Cost can also vary considerably, all depending on the size, application and material. As you can imagine, underwater drilling will employ a larger fitting than a small air hose used in a mechanics garage. Additionally, materials may change because of corrosive materials present or extreme temperatures.
