Slime Tube Sealant prevents flats by repairing punctures as they occur or treating existing punctures in the tread area of inner tubes. This is the ideal flat sealant for bicycles, motorcycles, yard tractors and other equipment with inner tube tires.

  • Repairs punctures up to 1/8 in. (3mm) using Fibro-Seal™ technology
  • Remains liquid inside the inner tube, coating the tread area as the tire rotates
  • Non-toxic, non-hazardous, non-flammable, non-aerosol and water soluble
  • Slime works repeatedly to repair new and existing punctures and lasts up to 2 years
  • Use 3 oz. to 24 oz. of slime per inner tube depending on size and usage

Important Information
