The Ultimate Tubeless Sealant Replenisher tyre sealant from SILCA is used to refresh the Ultimate Tubeless Sealant. This will extend the shelf life of your sealant by up to 1.5 years. You can also use it as a stand-alone sealant for particularly low temperatures down to -18 °C. It seals holes and cracks up to 7.5 mm in size in your tubeless tyres. Foaming latex and recycled carbon fibres from the bicycle, aircraft and automotive industries are used here. The carbon fibres used have a length of 6, 9 and 12 mm, which means that they seal particularly quickly and create a stable connection with the latex. This will prevent freshly sealed areas in your tyres from re-opening. If your tyre is completely flat, you can safely use a CO2 cartridge to inflate it without the sealant clumping.
