Rainbow 320 Chlorinator Body Assembly

This feeder body forms the sealed housing for the Pentair Rainbow 320 In-Line Automatic Chemical Feeder, where pool water flows past the sanitizer puck. It's the current-production new-style body, replacing a cracked, warped, or leaking body so the feeder holds pressure and doses correctly.

Compatibility

• Pentair Rainbow 320 In-Line Automatic Chemical Feeder
• Does not fit Pentair/Rainbow 320 old-style body feeders

What's Included

• Body only (no lid, O-rings, or internal fittings included)

Check the part number molded or stamped on the existing feeder body, or compare the body profile to the product photo, to confirm it matches the new-style body.

The Model 320 feeder was produced in an older and a newer body style, and the two are not interchangeable; R172321 is the new-style body only.
