Extra Large 29mm Black Oxygen-Absorbing Bottle Caps — Not Standard 26mm Caps

Important size warning: These are extra large 29mm crown caps. They are not the standard 26mm beer bottle caps that fit nearly every normal pry-off beer bottle.

If you are capping typical 12 oz beer bottles, 22 oz bomber bottles, or most standard pry-off crown-finish bottles, you almost certainly need standard 26mm oxygen absorbing bottle caps instead.

This 144-count pack of black 29mm oxygen-absorbing bottle caps is for rare bottle sizes that specifically require a larger 29mm crown cap. Use these only when you have confirmed your bottle takes a 29mm cap and your capper supports 29mm crowns.

Who Should Buy These?

  • Brewers using large-format or specialty crown-finish bottles that require 29mm caps
  • Customers who have measured their bottle finish or know the bottle manufacturer calls for 29mm crowns
  • Brewers with a compatible capper or 29mm capping bell

Who Should Not Buy These?

  • Most homebrewers bottling into standard 12 oz pry-off beer bottles
  • Most 22 oz beer bomber bottle users
  • Anyone looking for the common 26mm beer bottle cap size
  • Anyone using twist-off bottles, swing-top bottles, or cork-finish wine bottles

Need Normal Beer Bottle Caps?

If you found this page while looking for regular beer bottle caps, go to the standard 26mm caps instead:

Product Notes

  • Pack size: 144 caps
  • Cap size: 29mm crown cap
  • Color: Black
  • Liner: Oxygen absorbing
  • Use case: Rare large crown-finish bottles that require 29mm caps

Keep oxygen-absorbing caps dry until bottling day, since the liner activates when exposed to moisture. When in doubt, measure your bottle finish before ordering. The wrong cap size will not seal correctly.
