Groco Ff-2500 2-1/2"Npt X 2-3/4"Id Hose Barb

Used for connecting hose to valve, seacocks, strainers or any hardware having female NPT pipe threads. FF fittings are designed to accommodate the designed full pipe size flow and to provide an unrestricted passage through the fitting. If a 3/4" fitting is to provide full flow through the fitting, and also have a safe wall thickness, the fitting OD must be larger than 3/4". Therefore, a hose ID larger than the pipe size is required. Fittings are cast bronze. A hex nut is cast-in to allow for secure tightening.
