Additional Details

All of our domestic hoses are supplied by the largest manufacturer of fire hose in the United States. They have specialized in municipal fire fighting, industrial, military and marine hoses for the past 35 years. Every assembled hose is pressure tested by the manufacturer to ensure safety and reliability. Hoses are produced to meet applicable NFPA, UL, MSHA, FM, FDA and MIL‑H‑24606 standards.

Our Made in 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.
