Silca Ultimate Tubeless Sealant 946ML

Silca Ultimate Tubeless Sealant 946ML With a highly effective formula that works well even for high-pressure road tyres; the Silca Ultimate Tubeless Sealant 946ML (32oz) is temperature resistant for use down to -12°C; and provides a long-lasting seal for large punctures and holes up to 7.5mm. The secret to the efficiency and longevity is 6; 9 and 12mm chopped carbon fibres suspended within a foaming latex for even dispersion within the sealant. When a puncture occurs; the fibres are carried to the hole where they create a ‘dam’ against the tyre casing that is super stiff and strong; not only effectively fixing the puncture but also making a repeat far less likely.
