About this file
This document is an Attachment 1 contract item requirements specification for a 4" x 25' nonmetallic hose assembly for the Pearl Harbor Naval Shipyard (PHNSY) in Hawaii. The specification details a Texcel Gamma-Flex Tank 300 hose with high UV protection and abrasion resistance, designed for use as a temporary freshwater or saltwater header in marine environments. The hose must be 4" ID with brass cam and groove adapters at both ends, featuring a black nitrile tube, black corrugated neoprene cover, and high tensile tire cord reinforcement, rated for temperatures from -40°F to +190°F and 300 PSI working pressure.
Key technical requirements include hydrostatically testing each hose assembly at 300 PSIG for 10 minutes, visual inspection for defects, and certification of assembly standards. Each hose must be assigned a unique serial number, permanently marked on the ferrule. Vendors must submit manufacturer cut sheets with their quotes and may be required to provide a sample hose for destructive testing. Packaging specifications mandate careful handling to prevent damage during transit, with requirements for coiling, padding, and stacking. The document provides detailed specifications for end fittings, including specific part numbers for brass and stainless steel components from PT Coupling Co.
