Description

No more flats! Slime Tube Sealant seeks out and instantly seals punctures in your tubes up to 3mm. Install in your bicycle and enjoy two years of continuous flat tyre protection

When a puncture occurs, Slime's patented sealant is carried directly to the puncture. The pressure of the escaping air forces the particles into the opening, where they build up and intertwine to form a long-lasting, flexible plug. Instantly, air loss is blocked and a flat tyre is prevented


Non-toxic, non-hazardous and non-flammable

Effective under the most extreme temperatures: Low freezing point of -35?F (-37?C) and a high separation point of 182?F (82?C)

Uses Fibro-Seal technology

Valve core removal tool included in the cap of the bottle

Requires air

*Please note: The Slime tube formula should not be used in a tubeless tyre or in tyres traveling 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.*

FAQ

Q: How long does Slime Tube Sealant last once installed? A: Slime provides two years of continuous flat tyre protection once installed in your inner tubes, making it a long-lasting preventative solution.

Q: Can I use this sealant in tubeless tyres? A: No, the Slime tube formula is specifically designed for inner tubes only and should not be used in tubeless tyres. Use a dedicated tubeless sealant for tubeless setups.

Q: How does the sealant work when I get a puncture? A: When a puncture occurs, the escaping air pressure carries Slime's Fibro-Seal particles directly to the opening. The particles build up and intertwine to form a flexible plug that instantly blocks air loss and prevents a flat.

Q: Will this sealant work in extreme weather conditions? A: Yes, Slime is effective under extreme temperatures with a low freezing point of -35°F (-37°C) and a high separation point of 182°F (82°C), making it reliable year-round.

Q: What types of punctures will Slime seal? A: Slime seals tread area punctures up to 3mm. It will not repair sidewall punctures, snake bites, rim spoke punctures, or gashes from metal or glass. It's also not suitable for tyres traveling highway speeds greater than 45 mph.
