All-Weather Upgrade: No More Sticky Vents or Rain in Your Joe Junior

Upgrade your Joe Junior with a 304 stainless steel cap that delivers smoother airflow control, superior weather protection, and cleaner performance than the stock cast-iron top.

The Joe Junior Fitment Solution

Smaller kamado chimneys require an adapter for a snug, secure fit. This kit includes the high-temp silicone "donut" adapter that fills the gap between the Smokeware Cap and the Joe Junior’s chimney for a perfect seal.

Why Joe Jr. Owners Upgrade

  • Better Temp Control: Small domes react fast—the stainless slider provides smoother, repeatable adjustments.
  • Rain-Proof Cooking: The side-vented "chimney" design keeps water out so your charcoal stays dry in bad weather.
  • No Sticking or Seizing: Stainless steel won’t "glue" shut with grease like a cast iron daisy wheel can.
  • Stable Airflow: Side venting reduces "puffing" and wind interference during low-and-slow cooks.
  • Fast Fire-Ups: Need to get up to temperature fast? Just slide off the top vent piece to fully open the chimney for maximum airflow.
