Inspect the tube during every seasonal startup and replace it at the first sign of cracking, softening, or discolouration. Confirm the 3x7 size designation and 31.68 GPD flow rating match your existing tube before ordering, as feeder models accept different tube sizes and flow ratings that are not interchangeable.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54309092884755,"sku":"CAX-3512","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-santoprene-feed-tube-31-68-gpd-for-hayward-chemical-feeders-cax-3512-3.webp?v=1787032733","url":"https:\/\/poolaroo.com\/products\/hayward_cax-3512","provider":"Poolaroo","version":"1.0","type":"link"}
