Everything You Need to Repair a Flat and Keep Riding A flat tire doesn't have to end your ride. The Park Tool VP-1 Vulcanizing Patch Kit comes with everything needed to repair a punctured inner tube and get it ready for reinstallation and inflation. Together with the included vulcanizing fluid, the butyl patches form a molecular bond with the inner tube — creating a permanent repair for any puncture. The application process is straightforward: spread a thin layer of vulcanizing fluid over the area, let it dry, remove the patch backing, apply firm pressure at the edges, and inspect the bond after a minute or two. Six thin, flexible patches with tapered edges blend cleanly with the tube's profile, so repaired tubes roll smoothly without added bulk. The whole kit fits in a compact plastic box — small enough to slip into a saddle bag or jersey pocket — making it an easy addition to any ride kit. Patch Once, Ride for Miles Six patches total: two 25 mm round patches, two 19 mm round patches, and two 35 x 25 mm oval patches for a range of puncture sizes and cut types. Self-vulcanizing fluid bonds patches to the tube at the molecular level for a permanent, airtight repair. Thin, flexible patches with tapered edges conform to the tube's profile without adding noticeable bulk. Includes sandpaper for proper surface prep and printed instructions for in-the-field repairs. Compatible with butyl rubber and latex inner tubes found on nearly all bicycles. Compact plastic box measures 70 x 47.6 x 19 mm and weighs just 17 grams — fits any saddle bag or jersey pocket.
