About this file

This is a technical specification document for a freshwater or seawater fire main hose assembly required by Pearl Harbor Naval Shipyard & Intermediate Maintenance Facility (PHNSY & IMF).

The specification requires a 4-inch inner diameter, 15-foot-long hose assembly with nonmetallic construction featuring high UV protection and abrasion resistance for use in a marine environment with high UV exposure. The hose must have a minimum working pressure of 250 PSI, burst pressure of 1,000 PSI, rated bend radius of 16 inches or less, and continuous temperature rating of -20°F to 180°F. Construction requirements specify a nitrile rubber tube meeting ARPM Class B standards for oil resistance, reinforcement with synthetic textile fabrics and high-tensile wire helix, and a nonslip nitrile rubber cover with high abrasion and ozone resistance formulated to prevent cracking or failure for a minimum of 8 years. The hose shall be manufactured to ARPM standard IP-2 and assembled per NAHAD certification standards. End fittings must include brass 4-inch, 300 PSI heavy-duty male and female cam and groove adapters (PT Coupling Co. specified or equal) with four stainless steel locking arms on the female coupler, coupled using stainless steel crimp ferrules with no hose clamps permitted. All end fittings, ferrules, and one inch of hose at each end shall be painted fire engine red with at least 80 percent coverage. Hose branding shall include standard line markings, working pressure, date of manufacture, "PHNSY & IMF S/99," and contrasting 1-inch lettering. Vendors must provide manufacturer cut sheets with technical specifications and contact information, reference manufacturer part numbers, and submit sample hose assemblies for destructive testing at vendor expense if requested. Each hose assembly shall be hydrostatically tested at 275 PSIG for 10 minutes, assigned a unique serial number, and provided with written certification signed by the tester including test date, pressure, and duration. Or-equal offers require prior approval from PHNSY & IMF Code 260.8.
