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.\u003c\/p\u003e\n\n\u003cp\u003eNote: This listing is for the body only.

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.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53971992805651,"sku":"R172321","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-320-body-only-new-style-in-line-automatic-feeder-r172321.webp?v=1777322134","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_r172321","provider":"Poolaroo","version":"1.0","type":"link"}
