This large rubber O-ring seals the tank lid to the filter body on Onga Pantera and compatible cartridge filters. Manufactured from chemical-resistant, UV-stabilised rubber for durability in Australian conditions. A worn or cracked lid O-ring causes water to leak from around the tank lid.

Turn off the pump and relieve system pressure, then remove the tank lid and inspect the O-ring for cracks, flattening, or deformation. Replace if any damage is visible, or as part of routine filter servicing.\u003c\/p\u003e\n\n\u003ch3\u003eDoes this suit the Trimline MkII as well as the MkI?\u003c\/h3\u003e\n\u003cp\u003eNo — this O-ring suits the original \u003cstrong\u003eTrimline MkI\u003c\/strong\u003e. The Trimline MkII uses a different lid O-ring. If you have a Trimline MkII filter, please check the separate Trimline MkII lid O-ring listing or contact us to confirm the correct part before ordering.\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 lid groove, prevents pinching, and extends its service life.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48078155809043,"sku":"5311400","price":45.25,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/0591\/1827\/files\/OIP_42189f4d-1eb3-44f1-b0ab-fc34c1ae65b0.jpg?v=1707185458","url":"https:\/\/poolshop.com.au\/products\/onga-pantera-cartridge-filter-lid-oring-5311400","provider":"Pool Shop Australia","version":"1.0","type":"link"}
