Hydra-Shield Nylon Hydrant Caps
Nylon Hydrant Caps are only 25% the weight of cast iron caps, yet they withstand normal hydrant operating pressure and resist permanent deformation under stress. Capsizes with NST threads are made for 2.5 in., 4 in., and 4.5 in. hydrant outlets.

- Choice of colors provides an economical color code for fire hydrant flow and identification.
