An oily film at the hose ends, or an A/C that cools poorly, can point to a leaking hose, though other parts in the system can give you a weak A/C too. With the engine off, look the hose and its crimped ends over for oil stains, cracks or rubbed spots, and find out what is behind the problem before you buy. Pressure tests and any opening of the A/C system are a job for a shop.
The 2015-2016 GMC Sierra, 2015-2016 Chevrolet Silverado 2500 HD and 2015-2016 Chevrolet Silverado 3500 HD fit this hose, and so do other vehicles. If yours is not named here, look up its year, model and engine in the "Vehicles it fits" section.
