Product Description

5"" (127 mm) Storz x 4"" (101.6 mm) FNPT 30-Degree Storz Adapter secures fire hose to a fire sprinkler or standpipe system with a Storz connection and a sand-cast aluminum elbow designed to eliminate hose kinking. This Storz fire department connection installs to piping with National Pipe Thread (NPT), the most frequently used pipe threading standard for water-based fire protection systems in the United States.


When used as an FDC, each 5"" (127 mm) Storz x 4"" (101.6 mm) FNPT 30-Degree Adapter allows firefighters to pump water to fire protection systems when natural disasters, closed valves, or other problems interrupt the supply. Manufactured from heat-treated T-6 aluminum alloys, these adapters resist corrosion and wear and are hard-coat anodized in accordance with military standard MIL-A-8625 Type III for a smooth, hard finish.

NFPA-compliant fire sprinkler and standpipe systems require that each FDC also have an identification plate and protective cap (sold separately). This Storz adapter is within the NFPA 1963 Standards and Tolerances for Fire Hose Connections, and may be installed in accordance with NFPA 14, which permits the use of FDCs with large diameter hose when approved by the authority having jurisdiction (AHJ).
