Inner Tube Puncture Sealant

Protect your inner tubes against punctures with bike tyre puncture sealant from leading brands including Weldtite, Muc-Off and Slime. Inner tube sealant is added through the valve and works inside the tube to seal small punctures as they happen, helping to prevent flats and keep you riding for longer. Whether you're looking for Weldtite inner tube sealant, Muc-Off inner tube sealant or Slime for inner tubes, we have options for everyday cycling, commuting and off-road riding. These puncture sealants are designed specifically for use with compatible inner tubes and removable Presta or Schrader valve cores, providing an easy way to add extra puncture protection without carrying out a traditional puncture repair.
