About this file
This is a purchase specification for a hose assembly contract item. The government requires a fully assembled 4-inch ID by 25-foot long nonmetallic hose with high UV protection and abrasion resistance, featuring interlocking crimp ferrules and camlock adapters at both ends. The hose will be installed in Pearl Harbor, Hawaii, for use as a temporary freshwater or saltwater header in a marine environment with high UV exposure, and will be coiled and stacked for storage when not in use.
The hose assembly construction must utilize a Texcel Gamma-Flex Tank 300 (Part Number GTA30C1-4.0) with a black nitrile tube, black corrugated neoprene cover, high tensile tire cord reinforcement with dual helix wire, and a temperature range of -40°F to +190°F. End fittings must include a PT Coupling Co. 40EHD male cam and groove adapter at one end and a 40CHD female coupler (modified with STA-LOK II stainless steel cam assembly) at the other end, both coupled to the hose using PT Coupling Co. Pro-Grip C50SS crimp ferrules. Each hose assembly must be hydrostatically strength tested at 300 PSIG for 10 minutes with no leaks, weeps, bulges, or slippage allowed, visually inspected per NAHAD standards, assigned a unique serial number permanently marked on each ferrule, and accompanied by written certifications including tester signature, test date, and pressure/duration details. Vendors must submit manufacturer cut sheets with technical specifications and contact information and, if requested, a five-foot or longer sample hose assembly at vendor expense for government destructive testing. Hoses must be carefully packaged and palletized to prevent damage during transit, avoiding tight coiling, kinks, internal damage, and weight-induced damage to lower stacked units.
