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.
Five inch hoses with storz couplings are more common in the fire service than five inch double jacket hoses with expansion ring couplings. Also, five inch rubber covered hoses with storz couplings are in stock and less expensive.

- PSI Burst Test Pressure
5" Hose Male Couplings
- Inside diameter of a male coupling - 5" inches
- Outside diameter of a male NH / NST coupling - 6.26 inches (4 Threads per inch)
