Hose manufactured to this specification shall be of superior quality and workmanship. The hose shall withstand the rough usage of front line fire fighting. Hose specified shall meet NFPA 1961 standards. For North American customers, due to lack of verification of adherence to NFPA 1961 standards, import hose shall not be accepted. Hose furnished under these specifications, will have a potential service life and warranty of 10 years, barring mistreatment that would render it unfit for service. Upon delivery, the hose shall be free from defects in material and workmanship.

Jacket Construction:
Double jacket hose manufactured to this specification shall be tightly woven from entangled filament Nylon 6.6 yarn in both the inner and outer jackets and be highly abrasion resistant. The filler yarns of both the inner and outer jackets shall be high tenacity filament polyester for increased tensile strength and durability. The hose shall be resistant to most chemicals and petrol products, and resist deterioration due to exposure to UVrays and ozone. It shall not be affected by rot or mildew. The inside and outside jacket shall be manufactured with a minimum pick count of 11 picks per inch for increased strength and abrasion resistance. The inside jacket shall be manufactured using a reverse twill process to reduce friction loss. The inside jacket shall be manufactured on a circular loom in a clockwise direction and the outside jacket in a counter-clockwise direction. The hose must be of sufficient body and weight to meet the demands of heavy-duty fire fighting usage.

Abrasion Impregnation:
Hose assemblies shall be available with the special "Key-Lok" polyurethane based polymer impregnation for added abrasion resistance and ease in identification purposes. Impregnated hose shall meet the requirements of MIL-H-24606B for abrasion resistance. The standard color is high visibility yellow, green, orange or red. Other NFPA colors available upon special request.

The rubber lining shall be a single-ply extruded tube of synthetic high tensile EPDM compounded to resist ozone. The finished form shall be free of pits or other imperfections and have a smooth finish for better flow characteristics. The tube thickness shall be a minimum of .020". A thick wall rubber tube construction is available on special request. The adhesion between the tube and jacket shall meet a minimum requirement of 12 pounds on a 1 1/2" strip when tested in accordance to UL-19 standards. Minimum tensile strength requirements for the finished tube shall be 1800 psi. A valid USA/ULC Underwriters Inspection procedure shall be in force. A polyurethane liner meeting NSF-61 standards is available upon special request.

The minimum burst test pressure, when tested in accordance to NFPA 1961, on all Magnum diameters up to 3" shall be 1200 PSI/82 Bar. Minimum burst test requirements for 4" and 5" diameters shall be 900 PSI/62 Bar. Service test pressures stenciled on the hose shall be in accordance with current minimum requirements of NFPA 1962. A valid USA/ULC Underwriters 800 PSI/55 Bar listing shall be in force. Lengths available up to 100 feet.

Fire hose manufactured to this specification shall meet and exceed all performance requirements of NFPA 1961, Underwriter's Laboratories and MIL-H-24606B.

Magnum shall be coupled with 6061-T6 extruded aluminum threaded couplings or forged storz. Special threads or other custom features available upon request.

Key Hose reserves the right to modify any specification without prior notice to meet or exceed changing standards. Customers are advised special diameters or construction characteristics may be produced by special request. For more information please contact a Key Hose authorized distributor.
