If you have a manifold set similar to the one in the video, they can be disassembled and cleaned. Be careful with any o rings or seals. I would not do it if there is not real serious contaminants in the hoses or manifold. Low loss hoses are really a good thing to have. I really like them. In the video the service valves should have been backseated before removing the hoses. This removes any chance of losing a charge due a shrader valve failure. Ask me how I know.
