A socket-style PVC flange relies on a clean, undamaged pipe end for a proper solvent-weld bond. If the pipe end shows crazing or cracking, cut back to clean material before proceeding. Always replace the gasket — included in this kit — at every flange service interval, even if the old gasket appears intact.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-05-01 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":52770079670547,"sku":"357261","price":125.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-3-inch-flange-assembly-kit-with-gasket-and-stainless-steel-hardware-replacement-pool-spa-commercial-pump-357261-1.webp?v=1766525189","url":"https:\/\/poolaroo.com\/products\/pentair-3-inch-flange-kit-gasket-stainless-steel-hardware-pool-spa-commercial-pu-357261","provider":"Poolaroo","version":"1.0","type":"link"}
