1-1/2″ x 100′ Yellow Coupled Brass IPT/NPSH Rubber Covered Fire Hose (500 LB Test)

Description Rubber Covered Yellow 1-1/2″ X 100′ Coupled Brass IPT/NPSH (500 LB Test) Description 1 1/2″ Rubber Covered Fire Hose (500 LB Test) The rubber covered fire hose is manufactured to meet or exceed NFPA standard 1961, engineered to be durable and designed to remain flexible. Built to resist ozone, oxidation and most chemical / petroleum products. Made tough for extended service in rigorous use, yet virtually maintenance free. Hose Construction: The rubber covered fire hose is constructed from 100% synthetic yarn combined with nitrile rubber. Thru-the-weave manufacturing utilizes a circularly woven frame that is completely locked in with tough nitrile rubber to produce a single homogeneous unit. The laminated process consists of a 3-ply system, independently extruded and double vulcanized for maximum durability. The longitudinal ribbing reduces drag and provides for long service. The twill weave of the reinforcement resists puncture. Lining Properties: The tensile strength is 1500 PSI or greater, ultimate elongation is 400% minimum and the smooth nitrile rubber yields durability while minimizing pressure drop. This hose remains flexible down to – 35 degrees F and will resist heat up to 1200 degrees F for two minutes without rupture or damage to the synthetic reinforcement. Ozone Resistance: Hose shall show no visible signs of cracking to the lining or cover when tested in ac- cordance to ASTM D518 Procedure B (100pphm/118°F/70 hours). Chemical Resistance: Exposure to sea water and contamination by most chemical substances, hydro- carbons, oils, alkalis, acids and greases must have no effect on the short or long term performance of the hose. A chemical resistance chart is available and Key Hose will supply specific chemical resistance data on request of purchaser for unique applications. Heat Resistance: The hose, when subjected to a static pressure of 100 PSI, shall be capable of with- standing a surface temperature of 1200°F for a minimum of one minute without rupture or damage to the synthetic reinforcement. Pressure Ratings: 500# Acceptance Test Pressure 250# Working Pressure 750# Burst Pressure Temperature Range: – 4 degrees F   to    212 degrees F
