About This Item

The Pentair Short Feeder Tube (R172091) is the OEM replacement 5/8" OD short feeder tube for the Rainbow 320 In-Line Automatic Feeder.

What It Does

This short feed tube channels treated water through the Rainbow 320 automatic chemical feeder, maintaining consistent chemical delivery to your pool or spa. A cracked, brittle, or missing feed tube disrupts the feeder's flow path and compromises chemical dosing accuracy.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

When servicing the Rainbow 320 feeder, inspect all feed tubes — both short and long — at the same time. Tubes exposed to concentrated chlorine or bromine can become brittle over time. Replacing them as a set during a single service visit avoids a repeat disassembly shortly after.
