Product details

The Pentair R172321 is the replacement feeder body for the Rainbow model 320 in-line automatic chemical feeder. It is the genuine Pentair part.

The part that actually fails

An in-line feeder holds tablets in a plastic vessel with sanitized water running through it. That is a hard life. The chlorine attacks from the inside, sunlight works on the outside, and after enough seasons the body crazes, goes brittle and starts to weep at the wall or around a fitting. There is no reliable repair for a cracked feeder body, so it is replaced.

What you get

The body alone. The threaded cap, the control valve and the internal components are each their own Pentair part number, so order those alongside if yours are past their best while the feeder is off the line.

Get the model right

This body is for the model 320. Rainbow made several feeder sizes and the bodies are not interchangeable, so check the model stamped on your feeder before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

Is this a complete chlorinator?
No. It is the feeder body only. The cap, the control valve and the internal parts are separate Pentair numbers.
Which feeder does it fit?
The Rainbow model 320 in-line automatic chemical feeder.
Is it genuine Pentair?
Yes. R172321 is the Pentair part number for the Rainbow 320 feeder body.
Why would the body need replacing?
Tablet chlorine is aggressive and UV works on the plastic from the outside. Bodies craze, go brittle and eventually weep or split at the wall. Once that starts there is no repair, and the body is replaced.
