Whyte Seal.it Tyre Sealant

The Seal.it tubeless tyre sealant offers a perfect solution for those running a tubeless setup. Our formula comes ammonia free – optimised for use in road and mountain bike tyres running inner tubes or tubeless.

Our formula is recommended where wide tyres running low pressures are the norm.  Our formula enables gashes up to 5mm to seal instantly, whilst working safely between -20° to +80°.  This broad range allows the use of CO² cartridges without freezing or congealing, whilst also guaranteed to have no adverse chemical reaction with alloy or composite rims, tubes or tyres.

Our 150ml bottle comes with a built in one-piece applicator delivery system.  The innovative no-mess nozzle system works perfectly with Presta valves and comes with the required valve removal tool built-into the base.  The 150ml applicator bottle can be refilled using the 1 litre bulk bottle.
