As the tire rotates, the foam disperses carbon fibers evenly throughout, building a dam-like structure around any breach. That architecture is what allows it to \u003cstrong\u003eseal holes up to 7.5mm wide\u003c\/strong\u003e, a figure that puts most competing products well behind it.\u003c\/p\u003e\n\u003cp\u003eThe race-oriented formula is designed to run at high pressures without breaking down prematurely, and it's reported to be 400% stiffer than standard blends — meaning the seal holds under load rather than flexing open again. Pour it in at installation and it goes to work immediately on first puncture contact.\u003c\/p\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n\u003cli\u003eVolume: 500ml\u003c\/li\u003e\n\u003cli\u003eCarbon fiber content: 5% (recycled sources)\u003c\/li\u003e\n\u003cli\u003eMax puncture seal: up to 7.5mm\u003c\/li\u003e\n\u003cli\u003eCompatible with tubeless and tubeless-ready setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Silca","offers":[{"title":"Default Title","offer_id":43711419482156,"sku":"AM-AC-059-ASY-0101","price":24.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/silca-ultimate-tubeless-sealant-500ml-6432077.jpg?v=1771297147","url":"https:\/\/ricycles.com\/products\/silca-ultimate-tubeless-sealant-16oz","provider":"RA Cycles","version":"1.0","type":"link"}
