Park Tool Vulcanising Patch Kit

A flat tire doesn't have to spell the end of your ride. The Park Tool VP-1 comes with everything you need to repair a punctured inner tube and get it ready for reinstallation and inflation. Together with the included vulcanizing fluid, the butyl patches create a molecular bond with the inner tube, resulting in a durable permanent repair for any puncture. The application process is easy: simply spread a thin layer of vulcanizing fluid over the area, allow it to dry, remove the backing from the patch, firmly apply pressure (especially at the edges), and inspect the bond after a minute or two. Compatible with nearly all bicycle inner tubes. With everything contained in a small box, the VP-1 is an ideal size to tuck into a saddle bag or jersey pocket.
