This is the large O-ring that seals the multiport valve lid (cover) to the valve body on Astral and Hurlcon sand filter multiport valves. A worn or cracked lid O-ring causes water to leak from the top of the multiport valve. Replacing this O-ring restores a watertight seal and stops the leak.\u003c\/p\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eSuits Astral \/ Hurlcon multiport valves from \u003cstrong\u003eSeptember 2009 to current\u003c\/strong\u003e, including the following filter models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eECA550 \/ ECA650\u003c\/li\u003e\n\u003cli\u003eCA280 \/ C280\u003c\/li\u003e\n\u003cli\u003eFG604\u003c\/li\u003e\n\u003cli\u003eRX180 \/ RX280 \/ RX320\u003c\/li\u003e\n\u003cli\u003eE550 \/ E650\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number \/ SKU: 75919\u003c\/li\u003e\n\u003cli\u003eO-ring size: 40mm (lid\/cover seal)\u003c\/li\u003e\n\u003cli\u003eMaterial: rubber\u003c\/li\u003e\n\u003cli\u003eSuits: Astral \/ Hurlcon multiport valves (Sep 2009 – current)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow do I know if this O-ring needs replacing?\u003c\/h3\u003e\n\u003cp\u003eIf water is leaking from the top of your multiport valve — around the lid or handle area — the lid O-ring is the most likely cause. Remove the multiport valve lid and inspect the O-ring for cracks, flattening, or deformation. Even if the O-ring looks intact, if it has been in service for several years it may have lost its elasticity and should be replaced as a precaution when the valve is open for servicing.\u003c\/p\u003e\n\n\u003ch3\u003eDoes this suit pre-September 2009 Astral multiport valves?\u003c\/h3\u003e\n\u003cp\u003eNo — part 75919 suits Astral \/ Hurlcon multiport valves manufactured from September 2009 to current. Pre-September 2009 valves use a different O-ring. If you are unsure of your valve’s manufacture date, check the label on the valve body or contact us with your filter model and we can confirm the correct part.\u003c\/p\u003e\n\n\u003ch3\u003eShould I lubricate the O-ring when fitting it?\u003c\/h3\u003e\n\u003cp\u003eYes — apply a small amount of silicone-based O-ring lubricant (not petroleum-based grease) to the O-ring before fitting. This helps the O-ring seat correctly, prevents pinching during assembly, and extends its service life. Do not use petroleum-based lubricants as these degrade rubber O-rings.\u003c\/p\u003e","brand":"Pool Shop Australia","offers":[{"title":"Default Title","offer_id":50206674518291,"sku":"75919","price":12.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/0591\/1827\/files\/75919_large_16997cfa-9a76-47ec-bbfe-b617cc519058.webp?v=1734316884","url":"https:\/\/poolshop.com.au\/products\/astral-hurlcon-multiport-valve-lid-cover-oring-75919","provider":"Pool Shop Australia","version":"1.0","type":"link"}
