High Pressure Ring-Lock Clamp, 4"

The HPRLC400 is a heavy-duty 4" high pressure ring-lock clamp designed for secure, leak-free connections on aluminum irrigation pipe and fittings. Built to handle elevated system pressures, the ring-lock design provides a stronger, more reliable seal than standard clamps — making it the go-to choice for mainline connections, pump discharge lines, and other high-pressure points in your irrigation system. Fast to install and built to stay tight through the vibration and pressure fluctuations of daily irrigation operation.
