This polyester reinforced hose features a THV barrier layer that almost eliminates permeation. The CPE weather and UV resistant cover protects the hose from the elements while maintaining its flexibility. The grey cover not only offers a unique look, it helps to reduce heat absorption that can lead to vapor lock.
