This large O-ring seals the lid to the filter body on Astral Viron CL 400 and CL 600 series cartridge filters. A worn or cracked lid O-ring causes water to leak from the top of the filter.

Remove the filter lid and inspect the O-ring for cracks, flattening, cuts, or deformation. Even if the O-ring appears intact, if it has been in service for several years it may have lost its elasticity and should be replaced as a precaution whenever the filter is opened for cartridge cleaning or servicing.\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 in the groove, prevents pinching or rolling during lid installation, and extends the O-ring’s service life. Never use petroleum-based lubricants as these degrade rubber O-rings over time.\u003c\/p\u003e\n\n\u003ch3\u003eIs this a genuine Astral part?\u003c\/h3\u003e\n\u003cp\u003eYes — part 1005501 is a genuine Astral Pool spare part, not an aftermarket substitute. Using a genuine O-ring ensures correct dimensions and chemical resistance for pool water conditions.\u003c\/p\u003e","brand":"Astral Pool","offers":[{"title":"Default Title","offer_id":46805298479379,"sku":"1005501","price":64.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/0591\/1827\/files\/10055010oring.jpg?v=1693444941","url":"https:\/\/poolshop.com.au\/products\/astral-viron-cl-cartridge-filter-lid-oring-1005501","provider":"Pool Shop Australia","version":"1.0","type":"link"}
