Armored Textiles N50H4RR50S JAFRIB Standard Nitrile Fire Hose, 4″ X 50 Ft, 225 PSI, Red

JAFRIB is a superior nitrile rubber hose for use in supply and attack operations where resistance to petroleum, chemicals, and abrasion is critical. JAFRIB meets or exceeds NFPA 1961 Fire Hose Standard, 2013 edition.

Jacket Construction: Hose shall be made from 100% high tenacity synthetic yarn, circular woven and completely protected and locked-in by tough, highly ozone resistant synthetic nitrile rubber using a single through-the-weave extrusion process. This construction forms a single, homogenous construction without the use of glues or adhesives of any type.

Lining Properties: The tensile strength of the lining and cover shall not be less than 1750 poss., with an ultimate elongation of liner and cover not less than 500%. Permanent elongation shall not be greater than 25%.

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 16 pounds.

Accelerated Aging: Lining specimens subjected to an exposure of 158°F ± 3.6°F, for a duration of 96 hours 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.

Cold Resistance: Hose shall have the capability of use down to-35° 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-35° 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.

Heat Resistance: The ability of the hose to resist heat shall be verified using the test procedures defined in UL 19, Lined Fire Hose and Hose Assemblies, Heat-Resistance Test and FM Class Number 2111, Factory Mutual Approval Standard for Fire Hose, Heat Resistance. Hose shall withstand 1200° F for at least two minutes without bursting when subject to a static pressure of 100 psi.

Chemical Resistance: Exposure to seawater and contamination by most chemical substances, hydrocarbons, oils, alkalis, acids and grease will have no effect on the short or long term performance of the hose.

Inspection and Care: NFPA Advises users to develop a fire house inspection and care programmed based on NFPA 1962, Standard for the inspection, care, and use of Fire Hose Couplings, and Nozzles and the service testing of Fire Hose, 2008 edition. Such Program should also address the retirement of the hose.

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.
