I got my hoses from a AC shop in AZ that also has the correct muffler for my car. The owner said the biggest issue was tearing that special inside liner when slipping the hose over the fittings. He had me polish the fitting to remove anything that might damage that special liner. Then used mineral oil and heat on the hose. No leaks to date
Bob filled my system with R12.
