Armored Textiles N56H4FX450S JAFX4 4 Ply Fire Hose, 4″ X 50 Ft, 250 PSI, Yellow

JAFX4 is a unique, highly durable nitrile rubber hose for use in supply and attack operations where resistance to petroleum, chemicals, and abrasion is critical. JAFX4 exceeds NFPA 1961 Fire Hose Standard, 2013 edition.

Jacket Construction: Hose is manufactured using a four layer co-extrusion process to form a one-piece extruded hose with synthetic RLH cover. It is made from 100% high tenacity synthetic yarn, circular woven and locked in by tough, highly resistant synthetic nitrile rubber. The process produces a single, homogenous extruded through-the-weave hose without the use of glues or adhesives of any kind. Theco-extruded RLH cover material gives JAFX4 superior performance characteristics of abrasion, heat, chemical and age/ozone resistance over and above all other extruded hose products.

Lining Properties: The tensile strength of the lining and cover shall not be less than 2500 poss.. with an ultimate elongation of liner and cover not less than 500%.

Adhesion: The adhesion between the liner and the inside jacket is such that the rate of separation of a 1.5″ wide strip cut transversely, shall not be greater than 1″ per minute over a period of ten minutes, under a weight of 12 pounds.

Accelerated Aging: Lining specimens subjected to an exposure of 158° F ± 3.6° F, for a duration of 96hours shall be conditioned as per ASTM D 573, Standard Test Method for Rubber – Deterioration in an Air Oven. Then, the specimens shall be tested to ASTM D4112, Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers- Tension, Method A. Under evaluation, the tensile and elongation properties of the liner shall not be less than 75% of their initial values.

Abrasion Resistance: Outer jacket must withstand a minimum of 30,000 cycles on the Taber Abrase with no abrasion through the filler yarn. H-22 Calibrade wheel to be used with 1,000 gram load on each wheel. The hose shall also withstand Underwriters Laboratory Abrasion Test in UL 19, Lined Fire Hose and Hose Assemblies and the Abrasion Test defined in FM Class Number 2111, Factory Mutual Approval Standard for Fire Hose.

Cold Resistance: Hose shall have the capability of use down to-40° F. There shall be no apparent damage to jacket or lining when subjected to the following cold bend test: A 3-foot section of hose shall be exposed to a temperature of-40° F. for a period of 24 hours. At the end of the exposure period, the hose shall be rapidly bent 180 degrees back onto itself, first one way and then the other. Following this procedure, the hose shall not leak, nor show any damage to the jacket when subjected to the burst pressure shown above.

Warranty: ATI warranties both the hose and couplings to be free from defects in material and workmanship for a period of 10 years. Upon evaluation, hose found to be defective will be repaired or replaced by ATI at no charge to the fire department.
