Parktool Vulcanizing Patch Kit

The VP-1 includes six thin and flexible patches with tapered edges to blend with the tube’s profile. Packaged in a plastic box with sandpaper and instructions.

Four round patches, 20 mm and 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
