Park Tools Vulcanizing Patch Puncture Repair Kit

The Vulcanizing Patch Kit includes six thin and flexible patches with tapered edges to blend with the tube's profile. Each Kit Includes: (4) 25mm diameter round patches, (2) 25 x 35mm oval patches, self-vulcanizing fluid, sandpaper, and instructions in a small plastic box. Self-vulcanizing fluid bonds the patch to the tube at the molecular level.
