The Weldtite Dr Sludge inner tube is designed for children's bikes with 18-inch wheels and tyres 1.75–2.1 inches wide. It contains the correct dose of sealant: in the event of a puncture, centrifugal force pushes the sealant towards the hole, where the fibres seal it immediately with minimal loss of pressure.
It seals punctures up to 3 mm in diameter and works again in the event of subsequent punctures. The water-based sealant has anti-corrosion properties, does not dry out regardless of the external temperature and does not stick the inner tube to the tyre.
