Aluminum couplings are three times stronger than brass and weigh less. Move faster in demanding situations. Woven polyester material never needs drying and can be stored wet. Hose is immune to mold and rot. Can be stored for long periods of time without degradation. Can be run over with large trucks without bursting - even while pressurized.
