Its primary operational role is to sit flush within the dedicated structural mating channel positioned between the upper tank lid and the bottom half tank shell; when the exterior locking collar or Posi-Lok™ clamp framework is manually tensioned down over the seam, the cord ring undergoes high radial compression to establish an absolute watertight and airtight boundary. This robust pressure barrier prevents weeping and eliminates any localized bypass paths, allowing the pressurized filter tank to safely process massive hydraulic circulation volumes and sustain continuous internal system operating metrics up to 50 PSI without failing under sudden pump startup thrusts or intense mechanical vibration surges. Designed to endure decades of demanding outdoor pool pad weathering, relentless hydraulic cycling, and shifting seasonal thermal stresses, its advanced rubber matrix completely resists flattening, compression set, material brittleness, and advanced oxidative degradation from constant contact with pool chemical vapors and highly concentrated sanitizers like chlorine and bromine. \u003cspan class=\"citation-48\"\u003eDue to its thick-diameter, solid elastomeric core and broad circular footprint, this genuine replacement cord ring service kit carries a net product and shipping weight of approximately \u003c\/span\u003e\u003cb data-path-to-node=\"0\" data-index-in-node=\"2134\"\u003e\u003cspan class=\"citation-48\"\u003e1.00 pound\u003c\/span\u003e\u003c\/b\u003e\u003cspan class=\"citation-48 citation-end-48\"\u003e (about 16.0 ounces).\u003csup class=\"superscript\" data-turn-source-index=\"3\"\u003e\u003c\/sup\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53473438335087,"sku":"27001-0060S","price":40.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/270010061S-oring.png?v=1782831682","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-5-x-4-x-1-cord-ring-service-kit","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
