we had a mini-split installed at the house last year to warm/cool our enclosed porch. the unit came with and required ~25' of hose and cable. the installer said that the mfg (Daikin) install instructions state that the hoses and cables cannot be shortened or lengthened.
First all reputable manufacturers and distributors sell tubing kits in various lengths.
Second, there is nothing "magic" about the tubing ! It s standard HVAC tubing (NOT typically available at a big box store). That is insulated. The proper fitting can be brazed. The tubing from the factory comes "pre-charged" with refrigerant, so to do it "right" you would have to go with all custom tubing
(HVACS guys do this every day),
or install the long tubing, start and check that the system is running correctly, evacuate the system, cut the excess tubing out and splice the two piece back together.
