Inner Tube Puncture Sealants
Specially formulated by Flexel to give you a puncture protection system for certain wheelchair tyre tubes. In its simplest form; the gel like slime has a fibrous element to it that meshes together and blocks puncture holes, it clogs up holes and recreates and air tight seal. This stuff really does work and will be taking care of little punctures without you even knowing in many cases! Always check compatibility of your tyres/tubes with the instructions on the product.
