What Is It?

The South Park Corporation Hydrant Caps are replacement fire hydrant outlet caps designed to fit standard 2.5‑inch and 4.5‑inch hydrant connections. These caps protect hydrant outlets from debris, weather exposure, and mechanical damage while ensuring hydrants remain service‑ready for emergency operations.
