Park Tool Patch Kit VP-1

The VP-1 Patch Kit includes six thin and flexible patches with tapered edges to blend with the tube’s profile. Each kit is packaged in a small plastic box with sandpaper for cleaning the tube and instructions.
Four round patches, 25 mm in diameter, for smaller holes
Two oval patches, 25 mm x 35 mm, for wider cuts
Self-vulcanizing fluid bonds the patch to the tube at the molecular level
