Once dispersed within the system, the product finds the area of oxygen ingress and forms a polymer to seal the pinhole. Effective within 1-24 hours after application, the unique sealing efficiency of this market-leading water treatment chemical has been proven to not cause blockages or restrictions within the boiler or vulnerable system components such as pumps and safety devices. A leak can be quickly and efficiently sealed, without the need for a complete system drain down.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIdeal for reducing pressure loss from sealed systems\u003c\/li\u003e\n\u003cli\u003eSeeks out and seals inaccessible, internal microscopic leaks fast\u003c\/li\u003e\n\u003cli\u003eSaves time and money on draining down the system and repair costs\u003c\/li\u003e\n\u003cli\u003eSafe to use – does not cause blockages in pipework or vulnerable boiler components such as pumps, air vents and heat exchangers\u003c\/li\u003e\n\u003cli\u003eDesigned to be left permanently in the system – compatible with all metals and materials, including aluminium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"BAR\/F4","offers":[{"title":"Default Title","offer_id":45153764802808,"sku":"","price":36.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/0891\/0072\/files\/fernox-f4-500ml.jpg?v=1716282351","url":"https:\/\/www.zyberltd.co.uk\/products\/leak-sealer-f4-500ml","provider":"ZYBER","version":"1.0","type":"link"}
