Patch 20Mm Each

 What “20mm tube patches” are

20mm patches are:

• Small, round vulcanizing patches (~2 cm diameter)
• Designed for minor punctures (thorns, small nails, glass)
• Used with rubber solution (glue) for a permanent repair

They’re basically a slightly smaller version of the common 25mm patches.

 20mm vs 25mm patches (important)

 In practice:

Most mechanics prefer 25mm because it gives more coverage and margin for error.

 Practical advice

• ✔ Use 20mm patches for:
  • Small, clean punctures
  • Lightweight setups
• ✔ Use 25mm patches if:
  • You want safer, longer-lasting repairs
  • You’re unsure about hole size
• ✔ Always carry:
  • A few patches
  • Rubber solution
  • Sandpaper

 Bottom line

Your description is correct:

 20mm tube patches are small vulcanizing patches used for minor puncture repairs, commonly available from brands like Rema Tip Top and Vipal, either in bulk or kits.
