PENTAIR COMPRESSION NUT FOR RAINBOW CHLORINATOR (EE3) R172274Z

The Pentair Rainbow R172274Z Compression Nut is a genuine factory-original OEM replacement part designed for automatic chemical feeders [pentair.com]. This heavy-duty plastic locknut threads directly onto the feeder's inlet/outlet ports to clamp down on the chemical feed line tubing, creating an airtight, high-pressure compression seal. Replacing a stripped, cracked, or weathered nut stops active chlorine or bromine leaks, eliminates pressure drops, and prevents dangerous chemical spraying around your equipment pad.
