With a blue coating and durable elastomer construction, it resists chemical exposure and heat. When this O-ring fails, leaks, or causes a loss of pressure, it can reduce pump efficiency or damage other parts. Replacing the seal is quick and straightforward, and restores proper flow and pump performance.\u003c\/p\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eApply a thin, pool-safe lubricant to the O-ring before installation to help it seat correctly. Also check mating surfaces (diffuser \u0026amp; seal plate) for nicks or damage—any irregularities can cause leaks even with a new seal. Always have spares on hand, since O-ring degradation is common in pool service.\u003c\/p\u003e\n\u003ch3\u003eInstallation Tips\u003c\/h3\u003e\n\u003cp\u003eAlways shut off and lock out power before removing the pump diffuser. Ensure the old O-ring surface and housing groove are clean \u0026amp; dry. Lubricate the O-ring with a pool-safe silicone grease; do not over-stretch. Reassemble carefully to avoid twisting or pinching the seal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":46826148102310,"sku":"357098Z","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/9698\/1414\/files\/kentucky-pool-supply2_de34a401-3d14-4bd1-94c5-ec9b77f26b59.webp?v=1764107285","url":"https:\/\/kypoolsupply.com\/products\/intellipro-variable-speed-pump-pre-2019-parts-and-accessories-pentair-diffuser-o-ring-blue-coating-dyna-pro-pump-seal-357098z","provider":"Kentucky Pool Supply","version":"1.0","type":"link"}
