More Product Details

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 tire is prevented.

• Non-toxic, non-hazardous and non-flammable
• Environmentally friendly and cleans up with water
• Gallon size includes a pump for easy installation in all your tube tires. Great for shop use or home garages with multiple bikes. 
• Dispenses approximately 1 oz per pump
• Effective under the most extreme temperatures: Low freezing point of 14°F (-10°C) and a high separation point of 122°F (50°C)
• Uses Fibro-Seal technology
• Valve core removal tool included
• Requires air 

Please note: The Slime tube formula should not be used in a tubeless tire or in tires 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. Looking for automotive emergency tire sealant? Click here.
