Key Hose – Magnum / Maglite – Nylon 6.6 Double Jacket Attack / Supply Hose
Unique double jacket construction, combining the supple high strength of Nylon 6.6 yarn and polyester filament fibers to form a highly abrasion resistant outer jacket and an inner jacket with increased tensile strength and durability.
Unique double jacket construction, combining the supple high strength of Nylon 6.6 yarn and polyester filament fibers to form a highly abrasion resistant outer jacket and an inner jacket with increased tensile strength and durability. Our proprietary reverse twill weave construction reduces friction loss while ensuring the hose is lightweight, easy to handle and easy to pack. Customize the core of this double jacket attack line with your choice of a thin wall, high tensile, EPDM rubber liner (Magnum) or polyurethane liner (Maglite). Both of these dependable liner options provide superior kink resistance and eliminate ozone deterioration while maintaining the lightweight integrity of the hose. Maglite’s polyurethane liner material meets NSF (National Sanitation Foundation) Standard 61 for potable water. The outer jacket is mildew resistant and is also available with iconic “Key-Lok” polyurethane based polymer impregnation for additional abrasion and moisture resistance.
Scope
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. Magnum hose furnished under these specifications with an EPDM liner will have a potential service life and warranty of 10 years with a lifetime warranty against liner delamination. Maglite comes with our polyurethane liner and has a 5-year warranty against liner delamination, barring mistreatment that would render it unfit for service. Upon delivery, the hose shall be free from defects in materials 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 UV rays and ozone. It shall not be affected by rot or mildew. The inside and outside jackets 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
Hose assemblies shall come standard with the special “Key-Lok”
polyurethane based polymer impregnation for added abrasion
resistance and ease in identification purposes. Hose shall meet the requirements of MIL-H-24606 latest edition for abrasion resistance.
Lining
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″. The adhesion between the tube and jacket shall meet a minimum requirement of 12 pounds on a 11/2″ strip when tested in accordance to UL-19 standards. Minimum tensile strength requirements for the finished tube shall be 1800 psi. A valid UL/ULC Underwriters Inspection procedure shall be in force. A polyurethane liner meeting NSF-61 standards is available upon special request.
Couplings
Magnum/Maglite can be coupled with 6061-T6 aluminum threaded couplings or forged Storz. Special threads or other custom features available upon request. Barcode recess available at additional charge.
Performance
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. Lengths available up to 100′.
Standards
Fire hose manufactured to this specification shall meet or exceed all performance requirements of NFPA 1961 and MIL-H-24606 latest edition standards.
