Purpose

Used in kits

Alternatives

  • Sealant can ("fix-a-flat")— Faster but messy; can complicate a proper repair.
  • Plug kit + inflator— Handles actual punctures, not just slow leaks.

Maintenance notes

  • Run for 30 seconds twice a year to confirm it still works.
  • Check the hose gasket — the usual failure point.

Buying considerations

  • Auto shut-off at target pressure is worth paying for.
  • Check cord + hose reach: it must reach your farthest tire.
