Product Description

5" (127 mm) Storz x 6" (152.4 mm) FNPT Straight Storz Adapter threads on to pipe or fittings with National Pipe Thread (NPT), making this adapter ideal for use as a fire department connection (FDC). This Storz fire department connection threads directly to 6" (152.4 mm) male NPT pipe, serving as a compact, all-in-one alternative to standard threaded FDCs.

When used as an FDC, each 5" (127 mm) Storz x 6" (152.4 mm) FNPT Straight Adapter allows firefighters to pump water to fire protection systems when natural disasters, closed valves, or other problems interrupt the supply. NFPA-compliant fire sprinkler and standpipe systems require that each FDC also have an identification plate and protective cap (sold separately).


This Straight Storz adapter has a black-dyed exterior and non-dyed interior that are hard-coat anodized in accordance with military standard MIL-A-8625 Type III for a smooth and durable finish. 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).
