Maximise your cycling experience with this Slime Tube Sealant 1Gal Keg with pump. This powerful sealant prevents you from the trouble of dealing with flats by effectively sealing punctures in your tubes up to 3mm. Once installed in your bicycle, it guarantees two years of uninterrupted, flat tyre-free rides.

• The sealant's patented formula is directly transported to the puncture when it occurs. The escaping air pressure forces the particles into the puncture, creating a long-lasting, flexible plug that instantly blocks air loss and prevents a flat tyre.
• The large 3.8 litre size comes with a pump for hassle-free installation in a store, dispensing 28ml with each pump.
• To avoid clogging the pump with sealant, allow the excess sealant to gravity feed into the keg after use.
• This sealant is safe for use. It is non-toxic, non-hazardous and non-flammable.
• Effective in extreme temperatures from a freezing point of -35°F (-37°C) to a high separation point of 182°F (82°C).
• Utilises Fibro-Seal technology for enhanced performance.
• For your convenience, a valve core removal tool is included in the cap of the bottle.
• Air is required for the sealant to work effectively.
• Please note: The Slime tube formula should not be used in a tubeless tyre or in tyres travelling at highway speeds (greater than 45 mph). Slime sealants are designed to treat tread area punctures only and should not be used to repair sidewall punctures, snake bites, rim spoke punctures, or gashes from metal or glass.
