Aeroflow's new Kryptalon Series Ultra-Light Flexible Kevlar Braided Hose is the newest and up to the minute hose design in the market. Aeroflow's optimal and lightest hose combines a woven Kevlar braid with an internal smooth bore Teflon liner for greater flow capacity with a convoluted outer for astonishing flexibility. It also has significantly higher flow and pressure ratings than conventional convoluted Teflon hose. Ultra-Light has an average of 20% larger ID than ours (and other competitors) stainless braided Teflon hose and 14% larger ID than ours (and other competitors) stainless braided synthetic rubber hose.
