Description

Abrasion
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-24606 latest edition for abrasion resistance. NFPA colors may be specified by the end-user. A double dip process
for twice the abrasion resistance is available upon request.

Lining
The lining shall be a single-ply extruded tube of synthetic polyurethane to resist ozone. The polyurethane tube shall adhere to the jacket to prevent delamination. The finished lining will meet MIL-H-24606 and NSF-61 standards for potable water use hose. The use of the polyurethane lined fire hose is designed to increase packing ability
and reduce weight for fire fighting applications where lightweight fire hose is desired.

Couplings
Key-Lite shall be coupled with 6061-T6 extruded aluminum threaded couplings or forged Storz. Special threads or other custom features available upon request.

Performance
The minimum burst test pressure, when tested in accordance to NFPA 1961, on all Key-Lite diameters up to 3″ shall be 1200 psi / 82 bar. Minimum burst test requirements for 4″ diameter 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.

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. Hose furnished under these specifications will have a potential service life and warranty of 5 years, 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 with filament polyester yarn in the filler and ring spun polyester yarn in the warp of both
the inside and outside jackets. Inside jackets manufactured from 100% filament polyester would not meet Key-Lite minimum standards. 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 9.5 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 fire fighting usage.
