The logic behind flexible insulation is air space. The design of this hose creates one inch of captured air space between the stream of conditioned air and the outside air. Inflatable insulation between the inner and outer hose is the insulation.
There is no insulation mass to collect water and no insulation particles that could get into the aircraft.
Lock stitching attaches a TPU wear-strip in a spiral pattern.
This hose rolls up tighter and is lighter because there is no insulation material to compress or hold water.
The air-insulated hose is not just a super hose but rather an incomparable PCA Hose.
