Our "Made in the USA" double jacket lay-flat hose meets and exceeds all NFPA 1961 standards. This hose is constructed of an EPDM synthetic rubber tube and a double layer of 100% polyester woven jackets. The rubber lining is a single-ply extruded tube of synthetic EPDM compounded to resist ozone. Double jacket refers to the second layer polyester covering woven from staple polyester yarn added for increased abrasion resistance. Special reverse construction to reduce friction loss and a lighter hose.
