Colorful Stand Up Bubble Carb Cap has a rating of 5.0 stars based on 1 reviews.
This bubble style carb cap is made for using with your flat top bangers and works especially well with a beveled-edge banger to provide an air-tight seal.
The spherical bubble shape allows you to direct airflow around inside the bucket and push around your dab puddles.
Diameter measures 28mm at the widest point. Fits most flat top bangers.
