United States Coast Guard approved fire hose is typically 1 1/2" single or double jacket woven polyester firefighting hose fitted with NH/NST or NPSH/IPT brass couplings. The brass couplings allow for better corrosion resistance in harsh marine environments. USCG approved fire hose is manufactured to UL-19 standards as specified in CFR 118.320 Fire hoses and nozzles. It is labeled with UL approved markings and can be stenciled "USCG Approved".
CFR 118.320 specifies 1 1/2 inch diameter in 50 foot lengths for Coast Guard approval but FireHoseDirect can supply UL approved woven polyester fire hose in many diameter, length and color combinations as well as single jacket or double jacket construction if desired.
