Product Details
The Armored Textiles N50H15RR50N JAFRIB standard nitrile fire hose is a robust 1-1/2" x 50 ft hose rated for 300 psi, constructed to excel in supply and attack operations where resistance to petroleum, chemicals, and abrasion is vital. It meets or exceeds the NFPA 1961 fire hose standard, 2013 edition. The hose features a jacket made from 100% high tenacity synthetic yarn that is circular woven and fully protected by tough, highly ozone-resistant synthetic nitrile rubber through a single through-the-weave extrusion process, resulting in a homogenous construction without any glues or adhesives. The lining displays a tensile strength and cover strength of no less than 1750 psi, with an ultimate elongation of both liner and cover reaching at least 500%. Permanent elongation is capped at 25%, while adhesion between the liner and inside jacket ensures that separation does not exceed 1" per minute when measured with a 16-pound weight. The hose undergoes accelerated aging at 158°F ± 3.6°F for 96 hours, followed by testing to ASTM D4112 standards, ensuring that tensile and elongation properties remain above 75% of initial values. Additionally, it demonstrates cold resistance, functioning effectively down to -35°F without damage to the jacket or lining after a cold bend test at this temperature.
