PRIER C-144 Freezeless Wall Hydrant with Integral Vacuum Breaker – 1/2" MPT x SWT, 10" Insertion Length

The PRIER C-144 Series is engineered for year-round outdoor water access in cold climate conditions. Designed to connect to supply piping located within the heated portion of a structure, this freezeless hydrant automatically drains when shut off, protecting against freeze-related failures.
