You can so now buy a kit ! It includes :-- Valved Hose with connectors for modern fill points and Cans; Can of seal /refrigerent mixture; 2 cans of ` neat' refrigerent and instructions. Just bought one and re charged both my wifes Dodge Spirit and my Chev Malibu. Simple job and saved a bundle. The new gas is compatible with most new and older gases.
