About This Item
The Pentair R172321 is the OEM replacement feeder body for the Model 320 In-Line Automatic Chemical Feeder — the main housing component that forms the structural core of the feeder assembly.
The feeder body houses the chemical chamber and provides the sealed enclosure through which pool water flows and contacts the sanitizing agent. When the original body cracks, warps, or develops leaks, the feeder cannot maintain proper chemical dosing or hold pressure. This new-style body is the current production replacement for the Model 320 and restores the feeder to factory-original function.
Note: This listing is for the body only. Internal components, lids, O-rings, and fittings are not included. Confirm you are ordering the body specifically — not a complete feeder or lid assembly — before purchasing.

Pro Tip
The Model 320 feeder has been produced in both an older and a newer body style — and the two are not interchangeable. This listing is specifically the new-style body (R172321). Before ordering, confirm whether your existing feeder uses the new-style or old-style body by checking the part number molded or stamped on your current unit. If you are unsure, compare your feeder's body profile against the product photo before adding to cart.
